Because of the smocking at the waist, she can fit sizes medium through XL. This is a GORGEOUS, richly colored dress. Shes perfect for fall pictures! Think booties, wide brimmed hat and a beautiful field somewhere. 😍 It’s more of a satiny, somewhat shinier material, not like a flat cotton color. No stains or spots. Please see all pics as they’re a big part of an item’s description. Thanks for looking!
