When my kiddo was little I always followed 2 rules: Comfortable and Easy. Find a costume that isn’t complicated to get on (we all know how squirmy they can be), and is comfortable for them to wear. After all, kids are sometimes in costumes for a few hours. I always thought if I wouldn’t be comfortable in hard plastics and scratchy elastics, my toddler definitely wouldn’t be comfortable either.
