Vintage Blue and White Sundress

Homemade dress with no tags, purchased at vintage shop in 2021. Lightweight material, likely 100% cotton. Comes with matching belt. No stains or signs of wear. One external pocket on the front, no hidden pockets. Side has an opening with two snaps and one hook-an-eye closure. See measurements in pictures. I estimate this to be roughly a size 8. Pattern is small blueberries. 🫐 From smoke-free and pet-free home. Very cute and perfect for summer!
