These aren't clothes I made myself, but both the skirt and hat are handmade. Adelaide couldn't help but pose for some cute shots for you all!
Her hat was made by Party With Felt - https://www.etsy.com/shop/PartywithFelt
Her shirt was made by Battat, skirt came from a craft festival (the person no longer has a shop), socks are from American Girl, shoes are made by Springfield Collection.
