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.
