13 Halloween Costumes That Are Basically Pajamas

Halloween, though fun, can be one uncomfortable holiday. Tight costumes, itchy costumes, costumes that don't match the weather outside at all — it's tough to dress up and actually be festive. In case you're not down with spending the evening in uncomfortable knick knacks, though, don't worry: there are Halloween costumes that are basically pajamas out there. Because why would you spend an evening with a pile of candy in front of you any other way?

Just because you're going to be in pajamas does not mean you're sacrificing being cute on this notorious dress-up day. Comfortable is cute, especially when you're rocking an adult onesie. Honestly, would you want to wear anything else as you galavant from one Halloween party to another, collecting all the fun size candy bars offered in giant mixing bowls?

Adult onesies are warm. Late October typically isn't. This is just another reason why wearing a costume that's basically pajamas is the wisest, most adult wardrobe decision you could make this Halloween. In your youth you probably battled with your parents over the idea of wearing a turtleneck under your superhero costume. But as a responsible, don't-want-to-get-sick adult, the more skin is covered the better.

Thankfully the market is stocked with onesies for adults. Whether you want to be a bear, a unicorn, or a Jack-o-Lantern you'll be a comfortable bear, unicorn Jack-o-Lantern, on account of you will basically be wearing pajamas.

Adult Zipster Jack-o'-Lantern One Piece Costume

Keep it classic with a Jack-o-Lantern onesie costume.

This isn't a wear once and forget about it kind of costume. This is a multi-use piece of clothing fit for the pajama drawer.

It's perfect wear for Halloween to sleep.
