What are the rules for wearing black to a wedding in the UK?

Short answer

There are no legal rules about wearing black to a UK wedding. It is a matter of taste and respect, though some families still prefer guests avoid it.

Wearing black to a wedding in the UK is perfectly acceptable and has become common for evening and formal weddings. The old idea that black is only for mourning is largely outdated, especially for grown-up guests. A black suit or little black dress is a safe and stylish choice for most UK weddings.

Context still matters. For a daytime garden or beach wedding, black can feel heavy, so you might choose a lighter shade or add colour. For an evening wedding, black is often the most appropriate option. Always check the dress code on the invitation, whether it says smart casual, cocktail or formal.

Family and religious traditions vary. Some older relatives or certain faith communities may still view black as inappropriate for celebrations. If you know the couple's family holds these views, it is kind to choose another colour. When in doubt, ask the couple or a close family member for guidance.

There are no legal requirements about guest clothing in the UK. The main rule is to dress respectfully for the occasion and follow any dress code the couple has set.
