I purchased this costume in 12/24 mos for my daughtor. She is 16 months old and usually wears 18 months depending on brand sizing. This costume was too short. It rode up in the crotch area and once the hat is attached it's very constricting and seems to make the costume even shorter. It has mittens attached that don't have fingers....I don't think I would be able to get her to to keep those on anyways. Im not sure if my daughtor is tall or maybe this is made for a petit 24 month old. If your child is in the smaller percentile it might work. The quality is ok but I have to admit the cat face on the hood is not very cute. I am returning thsi costume and we will be making our own costume this year ;P
