Halloween gives you the perfect reason to show a little more skin than you normally would. And by all means, if you're feeling yourself this year and you're comfortable spicing things up, go for it! We spent most of 2020 covering ourselves up — even our faces were obscured by masks. Now with COVID-19 on the wane, it's time to flaunt what we have. Let 2021 be the least inhibited Halloween ever!
But do you want to do the expected thing, and be the hot girl in the catsuit? Or do you really want to go for it, and be the sexiest version of a hard seltzer out there? No matter what type of reaction you're looking for, these sexy Halloween costumes for women are right on trend. There are tried-and-true favorites (think pirates and pilots), sexy twists on popular costumes (hello, certain princesses) and even hot-blooded takes on viral memes. So do your thing and tell 2021 you can make anything (yes, even a horror movie icon or a vegan burger) sexy if you put your mind to it. (Just remember to stock up on fishnets!) And if you want to dress up with a sexy partner, check out our more subtle couples' costumes.
