The blue item is F.O KIDS size 90. The Mickey Mouse item is GAP Kids, 18-24 months. The polka dot item is H&M size 80. Each has different size markings. The Mickey Mouse item is unused. I may have washed it once, intending to wear it. The other two items were worn only once for a few hours at a wedding. Please note that there may be wrinkles from storage. They can also be used as outerwear.
