Costumes that start with B?

hey, any costume ideas that start with B. its for a costume party and i need to wear a costume starting with a B (i.e: bumble bee, barbie, box, boy band, etc.) but i kinda want to be something out of the ordinary yet at the same time cute and not crazy...if you get me hahaha. some of my friends are being bunnies and one is even being bruno...so thats kinda the range if you can see. thankss :)
