Black strappy, faux satin dress with adjustable ruched sides, size small

Black strappy, faux satin dress with adjustable ruched sides and low back, size small. Purchased from the online boutique Mussier. Never worn because I would need an XS. Would be best for a fuller chested person. Adjustable length and can be worn as a mini dress, midi or maxi. Also has adjustable tie straps. Measurements are 15 inches pit to pit, and 44 inches total length when the dress is not ruched up is
