A onesie is a one-piece pants outfit that’s become popular in the last few years. Even celebrities like Brad Pitt, Justin Bieber, and Miley Cyrus have embraced the onesie. They’re often made of fleece or polyester and can come with or without foot covers as well as with or without pockets. There are zippers or buttons down the front for getting in and out of them. Most have long sleeves and long pants, and sizes range from extra-extra small to 3X. Of prime consideration, especially when going to the bathroom, is the ease of getting a onesie on and off. Also, some are plain and functional while others are decorated with animal ears or other embellishments as Halloween or cosplay costumes.
