Morning dress is the daytime formal dress code, consisting chiefly for men of a morning coat, waistcoat, and striped trousers, and an appropriate dress for women.[1] Men may also wear a popular variant where all parts (morning coat, waistcoat and trousers) are the same colour/material, often grey and usually called 'Morning Grey' to distinguish it; this is only properly appropriate to weddings and races, and is known as a morning suit.[2]

Morning dress is now rarely worn as anything other than formal wear, as a form of Civic Dress e.g. by provincial Mayors (as an alternative to Court Dress), but more generally only for weddings, some official Civic, governmental or Royal functions, social 'Season' events e.g. races such as Royal Ascot, formal lunches (especially those in the City of London institutions notably of the Livery Companies and Guilds) and as uniform at some of Britain's most traditional schools such as Eton.

There is no specific suit for mourning, but it is customary to wear a dark suit and a black tie. Women traditionally wear a black net veil.
