No costume is complete without the right accessories and, for sexy retro costumes like flappers and Playboy Bunnies, that means hosiery. Backseam pantyhose are one of those tried-and-true hosiery options that draw a lot of attention to your legs and hindquarters, if that's what you're looking to highlight. Candy Apple Costumes carries this particular style in sheer black and nude. One size fits women up to 160 pounds.
