Onesies for kids are very different than onesies for babies. Kids’ onesies are usually more of a costume or pajama than a base layer or tee. We particularly like onesies that are cozy for sleep as well as for dress up. Look for solid stitching, smooth zippers, and ample openings from neck to inseam. Unicorns are having a moment right now, so many of our top choices reflect this trend. Look for plush, breathable fabric that is as comfy on the inside as it is on the outside.
