20 Best Halloween Onesies (For People Who Love Comfortable Costumes)

20 Best Halloween Onesies

Halloween is approaching fast, which means you probably came here because you're scrambling for a last-minute costume that will still get here on time if you order it now. Good choice, because otherwise you'll end up throwing together a really last-minute costume out of random clothes in your closet and inevitably spending the entire night trying to explain whatever pun or obscure TV character you sort of don't really look like to everyone at the party. We've all been there, and we're here to make sure you don't have to go there again. 

But first, a brief lesson in the modern history of women's Halloween costumes. 

Back in 2004, a certain teen movie declared the official ruling on sexy Halloween costumes.

The film in question was called Mean Girls (maybe you've heard of it?) and the pronouncement was as follows: "Halloween is the one night of the year when a girl can dress like a total slut, and no other girls can say anything about it."

It was a groundbreaking moment for Halloween, sex-positivity, and lingerie retailers everywhere. Cady Heron has spoken, and in the decade and a half that's followed, latex, lingerie, and animal ears have been the law of the land every October 31. 

However, just because you can doesn't mean you have to, and there's more to Halloween than just bunny ears and catsuits. 

Yes, super sexy Halloween costumes look fierce as hell. But think about it, pretty much every party (or hey, even every day) is an invitation to dress your sexiest. But how often is it socially acceptable to wear a onesie in public? 

It's not a rhetorical question. In the name of *journalism,* we've thought it over carefully and come up with a grand total of 3 scenarios in which you can wear a Halloween onesie without raising any eyebrows: 

1. You're a baby. I'm guessing we've all missed the boat on that one. 

2. You're the guy in the sandwich suit Miranda falls in love with in that one episode of Sex and the City. 

3. It's Halloween, baby. 

Yep, barring impossible and/or bizarre circumstances, Halloween is pretty much your only chance to rock a onesie these days, so might as well take advantage of it. 

And let's face it, onesies also have a bit of an edge on more traditionally sexy Halloween styles in certain regards. Anything latex and/or midriff baring? Not exactly ideal for filling up on booze and candy (which, if we're all being honest, is what Halloween is really all about, right?) With a soft, comfy, and relentlessly forgiving Halloween onesie, you're free to embrace the true spirit of Halloween and chug wine and gobble up candy to your heart's content.

Whether you're looking for something spooky, silly, or even sexy, there's a Halloween onesie perfect for whatever you have planned this year — with the exception of going to the bathroom, that is. You're on your own there.
