Onesie Pajamas FAQs

Are onesies for adults actually pajamas?

Yes. Every adult onesie on our site is designed as sleepwear. They are soft enough to sleep in and fun enough to lounge in, and you do not need to layer anything underneath.

How should adult onesie pajamas fit?

Relaxed and roomy, with enough length to stretch out without pulling at the shoulders or feet. Check the size chart on each product page, and if you are between sizes, most people prefer to size up for lounging.

Can I wash one-piece pajamas in the machine?

Absolutely. Machine wash and go. The combed cotton is easy to care for, and the fade-proof prints hold their color wash after wash.
