What do you get when you blend a matching sweatsuit set with cozy pajamas? One of the most *glorious* clothing items to ever exist: the onesie. Technically they’re the go-to sleepwear for babies, but those babies were onto something, IMO—hear us loud and clear when we say that if you haven’t tried an adult onesie, you’re missing out. From sexy cotton rompers to cozy fleece onesies in the perfect holiday plaid, there are some supremely comfortable adult onesies for women out there.
While not all of them are totally flattering, there are some you can even wear on a coffee run and look—dare we say?—chic as hell. Just drape a sweatshirt over your shoulders, sling a belt bag around your waist, and head out the door looking surprisingly put-together. Or, if you’re on the hunt for the perfect I-just-woke-up-like-this ‘fit for Christmas morning or something cute to wear to your annual holiday PJ party, don’t sleep on a festive onesie. There are romper options for hot sleepers and fleece versions that feel like the world’s nicest polar bear is gently cuddling you—there’s even a cheeky option with a cut-out flap right over the booty.
