You'll be laughing when you purchase an animal or cartoon character onesie with shoes and a tail. Just be warned, onesies are all about comfort. Tails may be hilariously funny, but they're not comfortable to sit on. They also tend to dangle down the toilet bowl in the middle of the night when you're half asleep. If you're going to wear a onesie, you might as well wear it well and you can't do that without a bit of swagger. Walk around like you've got the moves like Jagger.
