Sexy pink & floral lingerie

One piece, adjustable straps and back, elastic to tighten or loosen sides, snap bottom. Pretty gold stitch embroidery and sewn on floral petals. New in package. This size seems off, looks like a S-M to me. Pit to pit 16 inches. Not including adjustable straps, top to bottom 22 inches bra top to bottom. Stretches nicely. Cups appear to be to fit A, B, C Cup which I was so can tell! Maybe wrong size on package? So included the measurements and cup observation.
