These have spread to the point that almost all female costumes are 'sexy', and now the guy costumes are headed that way too. Remember when your options for Halloween were either a scary monster or Spider-Man? Can we please go back to that? Because there's nothing "sexy" about Big Bird.
The hardest part about this comic was pushing it past the point of reality. With a little research I found most of my gag costume ideas were actually real things real companies had produced. Well played, costume companies. Now I dare you to make 'sexy female LeVar Burton' or 'Paddington (the) Bear'.
