This costume is well made and very cute for my daughter! We had sizing issues. I ordered size "2T-4T" (which should mean XS) because my daughter is 3 years old, but it was too small! I reordered 'small' and it fits her just right, but I can see her growing out of it over the next year. My daughter is 41 and weighs 33 pounds. The small packaging says it's suitable for 3 to 4 year olds and I hope this helps some people who are unsure of what size to buy. It was very confusing in my opinion, hence I only gave 4 stars.
