Changing dress code

MPS wore wigs and tricorne hats

From the 16th to the 18th centuries, MPS often wore wigs and tricorne hats, and even carried swords as late as the 1700s. In the 19th century, top hats grew in popularity.

MPS would leave a top hat on a seat in the chamber to reserve their place with some even keeping a spare for the purpose. The fashion lasted a few decades into the last century. Now hats are banned. It is all about jackets and ties for men and for women, the equivalent level of formality. Other parliamentary quirks include bans on the wearing of armour and medals and carrying a briefcase.
