As you see in the photo, wearing men's suits can be a statement of gender neutrality and a rejection of the idea that clothing should be restricted based on gender. Maybe Lady Di in this way promoted the idea that anyone, regardless of gender, should be able to wear what they feel comfortable and confident in. Undoubtedly, in a men's suit, Princess Diana looked even more sophisticated and elegant. So take a look in your boyfriend's closet - there might be a suit in there that you can borrow from him.
