It’s time to start thinking about costumes for the year’s spooky festivities. If you’re thinking about something a little more chic that shows off your wilder side, then these 24 sexy plus size Halloween costumes are for you.

That’s right—not skinny, no problem!

There’s no reason why you can’t look and feel your best this Halloween, even if you’re not headed to a massive celebration. If you’re hooking up with a group of friends for a small shindig, these costumes will stand out.

Whether you’re going for something a bit more traditional or you want to go all-out with fun, we’ve got a costume choice or two that will suit your style.

Editor’s Pick: Plus Size Roaring ’20s Flapper Dress

It seems fitting that the perfect sexy plus size Halloween costume for 2021 is a flapper dress from the roaring ’20s, which is why the Roaring Roxy Flapper is this year’s editor’s choice.

If I have any Halloween parties on my dance card, this bad boy is going to be my number one pick. While it’s definitely sexy, I really like that it doesn’t seem to cheesy. Nor do you look like you’re trying too hard with it.

This costume comes with the dress and the headband included. The dress is made of a polyester gray mesh overlay with nylon and spandex in the dress. It has a back zipper, two tiers of fringe, and a sequence decorated headband.

Dalmatian Diva Costume

Since the origin movie dropped this year, Cruella de Vil is all the rage. So, why not dress up as the queen of evil this Halloween? If that sounds like your kind of gig, this Dalmatian Diva costume is for you.

This costume combines the fabulous Dalmatian style (though no pups were made during the making of it) with Cruella’s signature black, white, and red fashion. If you want to walk into the party with a fake cigarette holder and purr dah-ling all evening, this is the creative costume for you.

If you’re looking for a sexy plus size Halloween costume this year, this top-notch secret agent look is for you. There’s nothing sexier than zipping yourself into an all-black suit.

Firewoman Costume

I’m not convinced that fire departments are equipped to handle the fire you’re about to bring with this Firewoman costume. You probably won’t want to bring this bad boy to fire any real fires, considering it leaves almost nothing to the imagination, but it’ll definitely bring down the house. 

You’ll have to bring your own boots and hat to the party, but the short dress has reflected strips and metal hooks built into it to give you a real authentic(ish) look. Don’t forget to bring the respirator, in case you have any emergencies 😉
