This adorable outfit is a must have for your little cutie, it's super soft and so comfortable! The fabric we used is super stretchy and breathable, wait until you feel how soft it is! Made from a polyester/spandex blend, this fabric is a little thicker so the body of the peplum has some volume. It lays so nicely! This set is not made from bamboo These run about one size big, please size down if you want a true fit now. We do not recommend sizing up with this set. Please note runs big order one size down.
