Even if you rarely wear a cleavage-baring top on a Saturday night, Halloween is the one time of year where it's somewhat socially acceptable to let it all hang out. If you're looking for something that will flaunt your assets while also making your friends laugh (there's nothing hotter than a sense of humor, right?), you really should head over to Yandy.com. Whether you think they're downright ridiculous or totally genius, you'll get a kick out of their costumes such as a sexy Cat and & Hat or sexy Mario Brother. We found up some of our favorites here, but there are many, many more on the site.
