What makes a sexy costume the sexiest? There are some key components to the ultimate hot costume that will make guys drool. All costumes must have an insanely short skirt, especially if playing a fireman or a cop. All costumes must also have a low-cut shirt, especially if playing a taxi cab driver like in the “Hot Halloween Costume with Hot Chick” video below. A good rule of thumb for the ladies to remember is T.L.C: Tight, Leather, Cleavage. Lots and lots of cleavage. Halloween is a holiday after all and there is no better way to celebrate. One last note: No masks. We need to see what’s attached to the sexy costumes.
