"Grandson and grandmother love costume -- cutest Mario I've ever seen. SIZE: Ordered size S (4-6) and arm length and leg length need to be hemmed (3-4"). Fits grandson who is 4 yo, 40 lbs., 40" tall, 22" chest, and 20-1/2" waist. Body fits, but if your child is bigger than my grandson, order next size up. We do not use the blow up stomach so this gives a little added room to body of suit. Hope this helps as choosing a size is always the hardest part of placing an order."
"Toad costume (hat and vest) is precious and my grandson loves it. Fabric and workmanship is excellent. SIZE: runs small; ordered size small (4-6) for my grandson who is almost 4 and weighs 40 lbs, 40" tall, waist 20-1/2" and it is too small. Package states for age 3-4 -- but would really only fit a 2 yo or extra small 3 yo. Grandson's head is 20-1/2" and hat size works, but could probably use larger size. Hope this helps for choosing size - I looked at all comments and could not find where anyone actually gave their child's sizes. I'm ordering a medium (8-10) and hope this will work better. Whether it is Halloween, a birthday, etc., always can count on Celebrate Express for filling my needs."
