Onesie Animal Costumes

Everyone in Australia should have heard about onesies by now. If you haven't, you must have been living under a rock! Onesies are casual one piece jumpsuits often worn as PJ pajamas. They make excellent winter sleepwear and even fancy dress parties. Costume Collection is happy to offer a great range of animal onesies suitable as PJs, casual wear or even a Halloween fancy dress event.

Onesies are casual one piece jumpsuits often worn as Pyjamas. They make excellent winter sleepwear and are great to wear to Fancy Dress Parties. We have Animal and character Onesie designs available in unisex sizes.
