All of our children's products are American Apparel brand, made in the USA. Their size chart is an estimate but their items tend to run small so it is suggested to order one size bigger to allow room for any shrinking. Most items are 100% cotton or cotton blend; they are not pre-washed or pre-shrunk so they may shrink some, especially if you heat dry them. We recommend air drying or tumble dry on low heat.
