White tie (also known as evening dress or full evening dress in the United Kingdom) is the most formal dress code that exists for civilians today in the United Kingdom.In the United Kingdom civilian day court dress (in the Royal court) is similar to white tie, but nowadays white tie is worn in its place to the most formal state occasions, e.g. by foreign ambassadors at the State Opening of Parliament. This is the case even though such occasions occur during the day.
