# Black Tie Optional for Men: Tux or Suit?

Black tie optional means the hosts would like a tuxedo, but a dark suit with a white dress shirt and a conservative tie is fully acceptable. Wear the tux if you own one or the groomsmen are in them.

TL;DR: black tie optional means the hosts would like men in a tuxedo, but a dark suit with a white dress shirt and a conservative tie is fully acceptable. If you own a tux or the wedding party is wearing them, wear yours. Otherwise, wear your best dark suit with black oxfords.

The card says "black tie optional". You own one dark suit and no tuxedo. You're covered. This page goes past the one-line definition in the [men's wedding guest outfit](/blog/mens-wedding-guest-outfit) guide and walks through five outfits, the tux-or-suit decision, and what to skip.

*Both are correct at a black tie optional wedding. The tux is the hosts' first choice.*

## What black tie optional means for men

The Emily Post Institute puts it plainly. Men are requested to wear a tuxedo, but can opt for a dark suit. Its list for men has three lines: a tuxedo, or a dark suit with a white dress shirt and a conservative tie, plus leather dress shoes and dark dress socks.

So "optional" applies to the tuxedo, not to formality. A suit is allowed. A blazer with chinos isn't. Vogue's explainer quotes bridal stylist Anny Choi, who reads it as the couple wanting black tie without pressuring guests into buying or renting a tux.

On the ladder, it sits one rung under [black tie](/blog/mens-wedding-guest-outfit), where the tux is the rule. One rung down is [formal](/blog/formal-wedding-attire-men). There a dark suit is expected and a tux is a bonus.

## Tux or suit: how to decide

I'd wear a tuxedo if any of these are true:

- You already own one that fits.
- The groomsmen wear tuxedos and dinner is seated in a hotel ballroom.
- The wedding website says "black tie preferred" or shows photos from a formal venue.

A dark suit is the better call if you'd be renting just for this one night, if the wedding is in daylight, or if the venue is a garden, winery or barn with a formal invitation. Nobody at the bar will check whether your lapels are satin.

## 1. The classic black tuxedo

This is the outfit the hosts are hoping for. A black tuxedo with satin peak or shawl lapels and matching trousers with a side stripe. Under it goes a white formal shirt with a pleated or piqué front, fastened with studs. Add a black silk bow tie and a cummerbund or waistcoat. Shoes are black patent, with black socks.

Keep the pocket square white and the watch slim. A tie-it-yourself bow tie looks better than a pre-tied one once the evening loosens up, though no guest will be turned away for a clip-on.

## 2. Midnight navy or charcoal suit with a dark tie

This is the outfit most guests will wear, and it's correct. Pick the darkest solid suit you own. Pair it with a crisp white dress shirt, French cuffs if you have them, and a solid silk tie in navy, black or deep burgundy. Black cap-toe oxfords, a black belt and dark socks finish it.

*Emily Post's suit option, laid out on a bed.*

"Conservative tie" is the key phrase. Save the novelty print and the skinny knit for a cocktail wedding. A white linen pocket square, folded straight, does more than a colorful one here.

## 3. Black suit with a black bow tie

If you own a sharp black suit, you can push it closer to the tux look with a white shirt and a black bow tie. It isn't a tuxedo, and nobody will mistake it for one up close. From across the room, though, it sits comfortably next to the tuxes.

Keep everything else plain: no pattern on the shirt, black shoes with a real shine, no brown leather anywhere.

## 4. Summer or warm-weather: the ivory dinner jacket

For an evening wedding in summer, in the tropics or on a cruise, Emily Post's black tie guidance allows a white dinner jacket with black tuxedo trousers. At a black tie optional wedding, an ivory jacket with a black bow tie is a strong choice for a coastal or resort venue.

*An ivory dinner jacket for a warm evening. Keep the trousers black.*

Two cautions. The jacket should be ivory or off-white, and the trousers must stay black so the look doesn't read as an all-white suit next to the couple. If you can't find a dinner jacket, a lightweight navy suit in tropical wool is the safe summer answer.

## 5. Winter evening: dark suit, heavier wool, real coat

A December wedding is a good excuse for a charcoal or midnight navy suit in heavier wool or flannel, with a white shirt and a dark grenadine or silk tie. Black oxfords stay.

The part men forget is the coat. A dark wool overcoat looks right over a suit or tux. A puffer or a rain shell does not, so leave it in the car or check it at the door.

## "Black tie preferred", "creative black tie" and other wording

| Wording on the card | What I'd wear |
|---|---|
| Black tie | Tuxedo. A dark suit is a step down from what the couple asked for. |
| Black tie optional | Tuxedo if you have one. If not, a dark suit with a conservative tie. |
| Black tie preferred | Same as optional, but lean harder toward the tux. |
| Creative black tie | Tuxedo with one personal touch, such as a black shirt or a colored bow tie. |
| Formal | Dark suit and tie. A tux is allowed, not expected. |

When the wording is unclear, check the wedding website or ask someone in the wedding party what the groomsmen are wearing.

## What not to wear to a black tie optional wedding

- A light grey, tan or pastel suit. The code calls for a dark suit.
- A blazer or sport coat with odd trousers or chinos.
- Brown shoes, loafers without socks, or sneakers of any kind.
- No tie at all. An open collar belongs to cocktail and dressy casual.
- Novelty ties or a bow tie in the bridal party's exact color.
- An all-white suit, which competes with the couple.

## See the tux and the suit on your own photo

If you're stuck between renting a tux and wearing the suit you own, it helps to see both on you. On [TryAnyOutfit](/tryon), add a photo of yourself and a photo or screenshot of the outfit, and the preview goes on your real photo, not an avatar. Run it once with the tux and once with the suit, then compare.

It shows how the look reads on you. It won't tell you your size or how the jacket shoulders fit, so check the rental shop's measurements and try the real thing on before the day. It works on phones (iPhone and Android) and in the web Studio, and your credits are shared. It's cheap to start; current options are on the [pricing page](https://tryanyoutfit.com/#pricing).
