Very cute and retro strapless mini dress

Teal and black patterned retro style strapless mini dress with sweetheart neckline and peplum. I've actually never worn it, but I did sew up the back slit ( as I thought it was too short) but I can undo the 'seam' Marked as size small, but I think it's a xxs/xs or 0 The measurements are Bust flat 15" Waist flat 12.5" Hip flat 17 Total length 26" ( from highest point on bust)
