Floral mini dress with keyhole

Floral short sleeve mini dress. Lightweight, likely polyester or viscose. Keyhole slit in back at neck with button. Photo with measurements. Pit-to-pit approximately 21inches. Approximately size XL. No tags but I think I bought it at Top Shop when it was closing. All items come from a smoke-free and fragrance-free home. Items are washed in Tide Free&Gentle. We do have an adorable tri-pod kitty so her fur does tend to glitter our home.
