Blue/white ruffled, 3/4 sleeve mini dress, size 4

This is a new dress, worn once, ordered from Instagram post shop. It is polyester and runs small. It says medium, but it’s a small and I’d say a size 4. Great shape and super cute. Too small for me. Measures: shoulder to end of skirt 34”, waist to end of skirt 21”, arm pit to arm pit flat 17”, waist flat 14”. Smoke free/pet free house.
