FAQ:

Q: Are there any unicorn onesies for adults?

A: So many unicorn onesies for adults are big, bulky and perhaps a little less practical for wearing around the house. This onesie from Totally Pink is the ideal option for women who want cozy comfort, cuteness and lots less bulk. Instead of the common sagging crotch,…

Q: What kind of onesie has a star on it?

A: The brightly striped rainbow unicorn is another fun one that splashes stars over the pink, blue and white diagonal stripes. Because unicorns are so magical, it’s not surprising that this unicorn onesie is covered in a pattern of multicolored stars.

Q: What does a unicorn on a onesie mean for Pride?

A: This men’s fleece unicorn onesie features pride printed unicorns and pride themed cuffs at the ankles and wrists. In fact, even the unicorn’s horn comes in proper pride colors that represent life, healing, sunlight, nature, serenity and spirit. All those terms seem so appropriate for unicorns. Want to know more about the pride flag’s history?

Q: Which men’s cosplay onesie should you choose?

A: If you’re a man in search of a unicorn onesie, you might prefer the gray stars version of these pajamas. If you’re looking for a onesie with a more furry finish, this super thick fleece fur option would be perfect for outdoor cosplay.
