King George VI and Queen Elizabeth allowed the hemline of daytime skirts to rise

Formerly, men not wearing military uniform wore knee breeches of 18th-century design. Women's evening dress included trains and tiaras or feathers in their hair (often both). The dress code governing formal court uniform and dress has progressively relaxed. After the First World War, when Queen Mary wished to follow fashion by raising her skirts a few inches from the ground, she requested a lady-in-waiting to shorten her own skirt first to gauge the King's reaction. King George V disapproved, so the Queen kept her hemline unfashionably low. Following his accession in 1936, King George VI and Queen Elizabeth allowed the hemline of daytime skirts to rise. Today, there is no official dress code. Most men invited to Buckingham Palace in the daytime choose to wear service uniform or lounge suits; a minority wear morning coats, and in the evening, depending on the formality of the occasion, black tie or white tie.
