Black Tie Attire for Men: Every Piece of the Tuxedo Kit, and the Rules Around It
By Sukie Gao

The short answer
Black tie means a tuxedo. Emily Post's men's list is a black tuxedo jacket with matching trousers, a formal white shirt with studs and cufflinks, a black bow tie, a black cummerbund or a vest, black patent shoes and black dress socks. Braces are optional, gloves are not worn. A white dinner jacket replaces the black one only in summer, the tropics or on a cruise. A business suit does not meet the code.
Black tie attire for men is the one dress code where the list is fixed. It is not a mood or a level of effort; it is a specific outfit, the tuxedo (Americans say tuxedo, the British say dinner jacket or dinner suit), worn with a defined set of accessories. That makes it easier than semi-formal or cocktail, where you have to judge how dressy a suit is. It also makes mistakes easier to see. A long tie, a belt, a notch-lapel jacket or a pair of brogues each tells the room that something was improvised. This guide takes the black tie dress code for men one piece at a time. It starts with The Emily Post Institute's men's list and adds the cut details from Wikipedia's Black tie article, which draws on Debrett's and other etiquette references. It then settles the questions that come up once you own or rent the outfit: which lapels pass, when the white jacket is allowed, whether a dark suit is ever acceptable, and what to check at a rental fitting. Where the sources disagree, the disagreement is stated, not smoothed over.

The full kit, piece by piece
Emily Post's men's list for black tie is short. Each line is brief, so it helps to know what the piece looks like when it is right. The table below puts Emily Post's wording beside the detail Wikipedia's Black tie article gives for the same piece.
A few points the list makes that people miss:
• The jacket and trousers match. A black jacket over separate black trousers is not the outfit on the list.
• The shirt is a formal shirt, with a piqué or pleated front. An ordinary white business shirt with buttons down the placket is not on the list. Studs replace those buttons, and cufflinks close double cuffs.
• The cummerbund matches the tie. Emily Post asks for a black cummerbund to match the bow tie, or a vest instead. One of the two is part of the outfit, not an extra.
• Braces are listed as optional, but Wikipedia notes that tuxedo trousers have no belt loops and a belt is never worn. In practice, braces or side adjusters are how the trousers stay up.
• "No gloves" is written into the list. Wikipedia records that gloves and scarves were always worn until the mid-20th century; today they belong to white tie, where Emily Post lists white or gray gloves.
If every row in the table is covered, you are dressed. Anything you add beyond it, such as a pocket square or a boutonnière, is optional decoration and is covered further down.

Black tie for men: the list and the cut
| Emily Post's list | How it is cut (Wikipedia) | |
|---|---|---|
| Jacket | Black tuxedo jacket | Black or midnight blue; single-breasted with one button is typical; peak or shawl lapels faced in silk |
| Trousers | Matching trousers | No turn-ups, no belt loops; one braid down each outer seam matching the lapel facing |
| Shirt | Formal white shirt, piqué or pleated front | Turndown collar, marcella or pleated bib, double cuffs |
| Fastenings | Shirt studs and cufflinks | Studs usually silver or gold set with onyx or mother-of-pearl |
| Neckwear | Black bow tie in silk, satin or twill | Black, self-tied, matching the lapel facings |
| Waist | Black cummerbund to match tie, or a vest | Waistcoat or cummerbund, never both |
| Support | Dressy braces (optional) | Braces, hidden by the waistcoat; belts never worn |
| Hands | No gloves | Gloves were standard until the mid-20th century |
| Feet | Black patent shoes, black dress socks | Patent opera pumps or plain-toe oxfords; black silk or fine wool socks |
The jacket: lapels, color and the notch-lapel problem
The jacket is where a tuxedo is most often mistaken for a suit, so its details carry the code.
Color. Black is the reference. Wikipedia's article treats midnight blue as equally correct, and Gentleman's Gazette's buying guide lists "black or midnight-blue" as the two colors to choose from. Any other color, such as burgundy, gray or a pattern, moves away from the code. Wikipedia notes that color, texture and pattern became popular in warm-weather jackets in the 1950s, which is part of the white-jacket story below, not a license for a red tuxedo at a winter gala.
Lapels. Wikipedia says peak and shawl lapels are "equally authentic and correct", with the shawl slightly less formal. Both are faced in silk, usually satin or grosgrain, and the bow tie and trouser braid are meant to match that facing.
Notch lapels are the one jacket feature the article flags. It describes the notched lapel as "usually considered more appropriate for a business suit than a dinner jacket." Notch-lapel tuxedos are common, especially in rental stock, so this is not a reason to panic if that is what you have. But if you are buying, peak or shawl is the version no reference argues with.
Buttons and vents. The typical jacket is single-breasted with one button. Double-breasted is "generally considered equally appropriate" but less common now. On vents, Wikipedia ranks a ventless back as most formal and a center vent as least formal.
Fit still matters more than any single detail. A peak-lapel jacket with sleeves past the thumb looks worse than a well-fitted shawl collar, so leave time for alterations whichever version you choose.
Can you wear a dark suit to a black tie event?
Usually not. This is the question that splits black tie attire for men from every lower code, and the answer depends on what the invitation actually says, so read the exact wording before deciding.
Emily Post's wedding-guest guidance is direct. For a formal evening wedding, men wear a "Tuxedo (required if invitation states 'Black tie') or dark suit." So the dark suit is acceptable at a formal evening wedding only when the invitation does not say black tie. Once those words are printed, the tuxedo is required.
The dark suit becomes a full option one rung down. Under black tie optional, Emily Post lists the tuxedo or a dark suit with a white dress shirt, a conservative tie, leather dress shoes and dark dress socks. If your invitation says optional, read our guide to what black tie optional means; the suit route is covered there in detail.
There are settings outside weddings where a dark suit is accepted in place of black tie. Wikipedia notes that a dark lounge suit is generally acceptable at the opera, and that cruise lines including Cunard and Seabourn accept a dark suit on formal evenings. Those are house rules for those settings. They do not carry over to a black tie wedding or gala.
If you genuinely cannot get a tuxedo, ask the hosts before the day. Do not arrive in a suit and hope nobody notices. If they say a suit is fine, wear your darkest one with a white shirt and black shoes, polished. The verdicts below apply the sources to the common cases.

Tuxedo or suit? It depends on the wording
- Invitation says "Black tie"Skip itTuxedo required. A suit only if the hosts say so when you ask.
- Invitation says "Black tie optional"YesDark suit, white shirt, conservative tie, leather dress shoes.
- Formal evening wedding, no black tie wordingYesTuxedo or dark suit, per Emily Post.
- Formal daytime weddingYesEmily Post lists a dark suit, conservative shirt and tie, not a tuxedo.
- Cruise formal nightCheck firstSome lines accept a dark suit. Check your cruise line's own rules.
- Black suit with a black bow tie at a black tie eventCheck firstStill a suit: no silk facings, no trouser braid. Only with the hosts' OK.
Bow tie, cummerbund or waistcoat
The bow tie gives the code its name, so it is not a detail you can swap. Emily Post lists a black bow tie in silk, satin or twill. Wikipedia goes further: the only appropriate neckwear is a black self-tie bow tie that matches the lapel facings and the trouser braid. A long necktie does not appear on either list. Emily Post introduces the long tie only on the dark-suit route at black tie optional, where it asks for a "conservative tie". Wearing one with a tuxedo mixes the two codes.
Self-tied or pre-tied? Wikipedia specifies self-tied, and that is the version the references describe. If you have never tied one, practice a few times in the week before rather than on the day.
The waist covering is next. Emily Post asks for a black cummerbund to match the tie, or a vest. Wikipedia records a split here: the Emily Post Institute considers a waist covering essential, while Debrett's, the British etiquette publisher, no longer considers either one essential. For a guest in the United States, follow Emily Post and wear one. Its job is to cover the waistband and the shirt where it tucks in, which is the part of the outfit that looks untidy without it.
Whichever you choose, wear one and not both. Wikipedia is explicit: waistcoat or cummerbund, "but never both at the same time."
• Cummerbund. A pleated sash worn at the natural waist. The folds face upward. Wikipedia notes they were originally used to hold theatre or opera tickets. It is the lighter of the two to wear on a warm evening.
• Waistcoat. A low-cut evening vest. Wikipedia notes it hides the braces, which matters if you expect to take the jacket off later in the evening.
Keep both black. Wikipedia notes that the Black Tie Guide endorses deep, rich colors for the cummerbund, but a matching black set is the version on Emily Post's list.
Shoes, socks and the small accessories
Shoes. Emily Post lists black patent shoes. Wikipedia names two correct styles: patent leather opera pumps with grosgrain bows, which are the most formal, and black plain-toe oxfords in patent leather or highly polished calfskin. It rules out brogueing, the decorative perforations on wingtips, and describes open-laced derby shoes as generally too informal. Loafers, suede and anything with a rubber lug sole fall outside the list. If you will not wear patent shoes again, a pair of plain black calf oxfords, polished hard, is the shoe you can reuse for suits.
Socks. Black dress socks, per Emily Post. Wikipedia specifies black silk or fine wool, and notes that some guides recommend knee-length.
Pocket square. Optional, and Wikipedia says it is normally white. It does not need to match the bow tie or cummerbund.
Studs and cufflinks. Required by Emily Post's list. Wikipedia notes studs are most commonly silver or gold set with onyx or mother-of-pearl. Keep the studs and cufflinks matched to each other.
Watch. Wikipedia records that, traditionally, visible timepieces are not worn with formal evening dress, and that a pocket watch is acceptable. If you do wear a wristwatch, a slim one that sits under the cuff is the quiet choice; a large sports watch is the one to leave at home.
Boutonnière. Wikipedia says a flower may be worn, and lists red and white carnations, blue cornflowers and rosebuds as having been popular. At a wedding, check first: boutonnières often mark the groom and wedding party, and a guest wearing one can look like he is claiming a role.
Outerwear. Wikipedia notes that black tie events do not involve outerwear as part of the code, but an overcoat for arriving should be dark: black, charcoal or dark blue.
The white dinner jacket rule
The white jacket is the one sanctioned variation on the black tie dress code for men, and it has conditions attached.
Emily Post allows a white dinner jacket "in summer, in the tropics, or on a cruise," worn with black tuxedo trousers and the rest of the black tie kit. Everything else stays: the black bow tie, the formal white shirt, the cummerbund or vest, the black patent shoes. Only the jacket changes.
Wikipedia adds three useful details:
• The jacket is usually ivory or off-white rather than pure white.
• Its lapels are self-faced, in the same cloth as the jacket, rather than satin.
• In the United States it is frequently seen at weddings and formal beach events, while in Britain, through most of the twentieth century, white jackets were never worn, even on the hottest day of summer.
So the rule depends on where you are. A July black tie wedding on a terrace in the American South or a Caribbean resort is the white jacket's home ground. An October hotel ballroom is not, whatever the weather outside. If in doubt, black or midnight blue is never wrong in any season.
Two traps to avoid. First, Emily Post pairs the white jacket with black tuxedo trousers; white trousers are not part of the code. Second, at a wedding, check what the groom and groomsmen are wearing if you can find out. If the wedding party is in white jackets, a guest in the same thing can be mistaken for one of them. Black keeps you clearly a guest.
Renting or owning, and what to check either way
Both are normal. The right choice comes down to how often you will wear it, and whether you can get a good fit.
The case for owning. Gentleman's Gazette's tuxedo buying guide argues strongly for buying. Its reasoning: rental jackets usually have a fused interlining, which is warmer to wear; the armholes are often cut full, which makes raising your arms uncomfortable; and rental shops tend to stock "gimmicky styles, heavily-worn garments, poly-blend shirts and vinyl footwear." It also notes that a man with a tuxedo in his closet tends to accept more formal invitations. If you expect several black tie events over the next few years, such as weddings, galas or award dinners, owning a classic version makes sense. The same guide's buying specification matches the references above: a black or midnight-blue, single-breasted, one-button jacket with shawl or peak lapels faced in grosgrain or satin.
The case for renting. For one wedding, or if your weight is changing, renting is the practical answer. Check exactly what the package includes: the shirt, bow tie, cummerbund or vest and studs are the pieces most men do not own, and they are easy to forget until the morning of the event.
Whichever route, check these at the fitting, using the kit list above:
1. Lapels are peak or shawl, and faced in satin or grosgrain.
2. The trousers have a braid down the outer seam and no belt loops.
3. The shirt takes studs and has double cuffs, and the collar fits with a finger's room.
4. You have been given a black bow tie, not a long tie or a colored one to match a wedding palette.
5. You have a cummerbund or a waistcoat, not both, in black.
6. The jacket sleeve shows a little shirt cuff, and the trousers sit on the shoe without pooling.
7. The shoes are plain black lace-ups or pumps, not derbies or loafers.
Collect it early enough to try it on at home with the shoes and socks. Fixes are easy two days out and impossible two hours out.
Black tie at a wedding: timing, wording and what changes
Black tie is an evening code. Wikipedia notes it is traditionally worn only after six o'clock in the evening, or after sundown in the winter months, and cites an etiquette reference that weddings before 6 p.m. are not usually black tie unless specified. Emily Post's wedding-guest page gives men a dark suit, conservative shirt and tie for a formal daytime wedding. So if a ceremony starts at 2 p.m. with no black tie wording, a tuxedo would overshoot; if the invitation does say black tie for an afternoon ceremony, wear it, because the hosts have told you to.
Read the exact words. Emily Post says the invitation and the time of the wedding are your best guide to formality. Four wordings come up:
• "Black tie." The tuxedo kit above. A suit only if the hosts tell you otherwise.
• "Black tie optional." A tuxedo is welcome; a dark suit with a white shirt and conservative tie is acceptable. See what black tie optional means for the full breakdown.
• "Formal." Emily Post's formal evening entry is a tuxedo or a dark suit. Either is right.
• "White tie." A different code above this one: tailcoat, white vest and white bow tie. A tuxedo is not enough.
Two wedding-specific points. First, Emily Post notes that the nature of the service (secular or religious) and local custom also shape what you wear, and that some parts of the country are more conservative than others. In a house of worship, keep the jacket on. Second, at black tie events a guest is dressed in the same uniform as everyone else, including, often, the groomsmen. That is fine. What separates you is that you are not wearing their matching tie color or boutonnière.
Get those right and the rest of black tie attire for men is the fixed list at the top of this page. For the other dress codes you might see on a men's invitation, from white tie to casual, our wedding dress code for men guide covers each one.

Frequently Asked Questions
Quick answers to help you find the perfect wedding guest dress.
A tuxedo: a black (or midnight blue) tuxedo jacket with matching trousers, a formal white shirt with studs and cufflinks, a black bow tie, a black cummerbund or a vest, and black patent shoes with black dress socks. That is The Emily Post Institute's men's list. It is an evening code, traditionally worn after 6 p.m.
Yes. Wikipedia's Black tie article treats black and midnight blue as the two correct colors, and Gentleman's Gazette's buying guide recommends either. Emily Post's list names black, so if you want the version no host will question, black is the default. Midnight blue is the only other color in the references.
