I ordered a 18 month size for my 9 month old grandchild. He weighs 18-1/2 lbs, but the sizing was so very off, he was unable to wear this outfit. I ordered a larger size based upon other reviews, washed in cold water and let air dry. There is no way this would have fit his wrists or ankles. The outfit is very cute, did not fade but it was a total waste of money on something he could not wear. I would not recommend this unless you order something three times the size you need.
