It's tux season again, and my girlfriend has very strong opinions about my suit. She prefers spread collar to wing, straight tie to bow, and thinks my patent oxfords look feminine. Predictably, she also hates the cummerbund and isn't crazy about peaked lapels. She (rightly) says that most men at black tie functions dress the way that she recommends. How to I explain to her in a way that she'll understand? She actually said that I will embarrass her if I wear the outfit that I have.
