What should i wear to a Quince?

im going to a Quince on Saturday:) i have a lot of dresses but i want to look really cute. to be honest.. i don't have a very large bust, but a huge butt. im looking for something more like a cocktail dress and not too long. i don't want sparkles either because im not very girly. i really like animal print but im willing to wear any pattern that will look good on me :D
