I want to know the answer to the following question:
From what century were men's knee breeches worn at Buckingham designed in?
All the background I'm provided with is that "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.". Is that enough to answer the question?
