What should I wear to a black tie wedding as a guest?

Black tie is the most formal dress code you will usually see at a UK wedding. For men, the classic choice is a dinner jacket with matching trousers, a white shirt and a black bow tie. A dark formal suit with a tie is also acceptable if the couple has said so. For women, a floor length evening gown is traditional, but a sophisticated midi or cocktail dress can work if it feels formal and elegant. Avoid anything too casual like denim, linen or bright daytime prints.

Think about the venue and season. A winter wedding in a grand hotel calls for richer fabrics like velvet or silk. A summer black tie wedding in a garden might allow lighter colours and breathable materials. Always check the invitation for extra notes, such as a colour palette or a request for lounge suits. If you are unsure, ask the couple or another guest. Black tie is about looking polished and respecting the occasion. Comfort matters too, so choose shoes you can dance in and a jacket that fits well. Accessories should be understated, and jewellery can be simple or statement, but never flashy.
