Wedding guest dress codes, decoded

Dress codes on wedding invitations are one of the most-asked questions from confused guests, largely because the terminology is used inconsistently across different regions and generations. A clearer breakdown helps both guests and the couple deciding which one to use.

White tie

The most formal, rarely used for weddings: a full tailcoat for men, floor-length formal gowns for women. If you're using this term, expect to genuinely need to explain it, since most guests won't own the right clothing without guidance.

Black tie

Tuxedos for men, formal floor-length or elegant cocktail-length gowns for women. This is a real commitment for guests, factor that into whether it suits your actual guest list.

Black tie optional

A dark suit is acceptable alongside a tuxedo for men; women have more flexibility between a formal gown and an elegant cocktail dress. This is the most commonly misunderstood tier, guests often default to business formal when the couple intended something a step up from that.

Cocktail attire

A suit (not necessarily dark) for men, a knee-length or midi dress for women. This is the most common modern wedding dress code and the one with the widest acceptable range.

Casual or dressy casual

Still means dressed up relative to actual everyday casual wear, not jeans and a t-shirt. A collared shirt and nice trousers for men, a sundress or smart separates for women, is a safe read of this code.
