What should I wear?
Our dress code is Formal (Black Tie Optional).
OK, but what does that mean?
Get as glamorous as possible while still maintaining enough range of motion to bust a move on the dance floor.
That doesn't help at all, what is wrong with you?
Unfortunately there's a text limit, so we can't really get into that. For suit-wearers, tuxedos are not required but can be worn if preferred. For the rest, floor-length gowns, fancy cocktail dresses, or dressy jumpsuits/pantsuits are recommended.
