Size Medium. Laid flat the garment measures approximately 18.5” across the bust. Flawed item. Last three pictures shows thread missing on one of the floral eyelets, and two little black pen mark dots by the buttons. Other than that, the fabric is crisp and clean. I did such a poor job inspecting this item before accepting the order ☹️ It’s already too big for me to begin with. If you don’t mind the flaws, please take this off my hands.
