Halloween is the holiday of make-believe. And for adults, it's the perfect time to wear something a little sexy, or even better, a little gory and sexy. You could dress up as a sultry nurse, of course. But what about a sultry zombie nurse, with bitemarks and hollowed out eyes? That's even better.

The best adult costumes are a little subversive; they're visual concepts that break norms and are self-aware about what they represent.

But the costumes on this list? Are none of those things. These are the "sexy" costumes that make you laugh and think, "Who thought this was a good idea?" At best, they're kind of corny. At worst, they're kind of creepy, and not in a Halloween-type way. But they're all real—and they're all available for purchase—if you feel like making an impression this holiday season.

Forget the plaid skirt, the cheerleader outfit, and even the leather bodysuit. Here are the 15 weirdest sexy halloween costumes you can actually buy online Halloween 2025.
