The Design on these looks nice. I like the color and the feel of the fabric. My son is between 2t and 3t in clothes. He hates wearing the pj’s too snugly, so I got a 3t. It fits him loose, but not loose like if he is swimming in it. It fits like a regular pj set. If your kid doesn’t mind the fit, get their size, but if they are bothered by it fitting snug,size one up.See full review
