Soft and stretchy, our dresses are easy-care and very comfy for bub. The sizes up to and including size 1 come with a snap underbody to go over a nappy. Size 2 and over doesn't have the snap body feature. We have really focused on the details and ensured the dresses up to size 1 are short enough so that a baby can crawl and not trip over the skirt. Size 2+, when they're walking, is a bit longer. All Snuggle Hunny clothing is made with GOTS Certified Organic Cotton CU 1182228. Sienna is part of our Enchanted Forest collection.
