Most costumes come off the moment the photos are done. This one is cut as loungewear first, so it reads as a full animal outfit at a party and then stays on for the rest of the night.

The loose unisex fit leaves room for regular clothes underneath at a cold outdoor party, or almost nothing underneath for a night at home.

Key Features:

  • Gets worn more than once a year: built as a pajama, so it earns wear on cold mornings long after October
  • Nothing to assemble: a single piece that goes on in seconds, with no separate parts to keep track of
  • Works for a group without sizing headaches: the loose unisex cut fits women and men from the same size range
  • Layers when the party is outdoors: enough room in the cut for a shirt and leggings underneath
  • Stays comfortable for a full evening: soft one-piece construction rather than stiff costume fabric
  • Reads as a real costume: the animal design carries the look on its own without accessories

Frequently Asked Questions

Is this a costume or actual pajamas? +

Both, which is the point. It is cut as soft loungewear rather than stiff costume fabric, so it works as a full animal costume at a party and stays comfortable enough to keep wearing afterward.

Does it fit women and men? +

Yes. The cut is loose and unisex across the full size range, so there are no separate men's and women's versions to choose between.

Which size should be ordered? +

Sizes run S through XL in a loose fit. Anyone between sizes, or planning to wear clothes underneath for an outdoor party, should size up.

Can clothes be worn underneath? +

Yes. The loose cut leaves room for a long sleeve top and leggings, which is worth doing for a cold outdoor party or a walk between houses.

Is it warm enough for outdoors? +

It is a soft one-piece garment rather than a coat. For a mild evening it is enough on its own, and for a cold night a base layer underneath and a jacket over the top handle the rest.

How does it wash? +

Machine wash cold on a gentle cycle and hang it to dry. Washing it separately the first time is worth doing, and bleach should be avoided entirely.

Does this work for a group costume? +

Yes. The same design runs across every size, so a friend group, couple, or household can match without assembling separate pieces for each person.

Does anything else come with it? +

No. The onesie is the complete outfit and arrives as a single piece, with no separate accessories needed to finish the look.

How long does shipping typically take? +

Orders are processed within 1–2 business days, and delivery typically arrives in 7–10 business days. Tracking information is provided once your order ships so you can follow its progress every step of the way.

Please read our Shipping Policy for more information.

What if this isn't right for me? What's the return policy? +

Every TENAX product is backed by a 30-day return policy, giving the opportunity to try it and ensure it meets expectations. If it doesn’t feel like the right fit, returns are available within 30 days of delivery in accordance with the return guidelines.
