Windsor uniform

[2] The full dress version, which had a good deal of gold braid about it, did not survive beyond 1936, but the undress version, introduced in 1798,[3] is still worn today: a dark blue jacket with red facings.

The uniform currently takes the form of an evening tail coat of dark blue cloth, lapelled, with scarlet collar and cuffs.

[1] There are three buttons on each front, two at the back of the waist, two at the end of each tail, and also two on each cuff (plus one above).

It is worn with a white single-breasted waistcoat with three small gilt buttons of the same pattern, and with plain black evening-dress trousers.

As well as the tail coat version, the late Duke of Edinburgh also wore (and King Charles III continues to wear) a dinner jacket version of the coat.
