An adult wearing footie pajamas may seem a little silly, and maybe it is, but it is comfy and it is fun. Wearing a onesie may make you feel like a kid again, and that is perhaps part of the appeal. For many people, connecting with their childhood makes them feel a certain security and peace of mind. Theses types of jammies are available in many colors and fabrics, and as with any other garment, you should check the manufacturer’s instructions before washing.
Three examples that look really comfy to me:
