Black caftan style long dress with brown and golden beige embroidery Size M/L

Lightweight silky caftan style long dress with flattering sweetheart neckline, bracelet length sleeves, and side slits. Embellished with lavish embroidery at front neckline, sleeve hems and front of side slits. Embroidered covered buttons add detail on front bodice. Lightweight silky fabric which I think is polyester. The interior of side seam allowances and sleeve seam allowances are frayed. It's a very easy fix. Doesn't affect how it looks while wearing. All other seams are finished. Beautiful beach cover up, festival wear or as a robe. Measurements indicate a size M/L but there are no tags. I think this would best suit a smaller size and worn with lots of ease, but it's a personal fit preference. Please see all measurements below. Approximate Flat Measurements: Pit to pit 22" Width at bottom hem 33" Length shoulder to hem 48" Sleeve seam 17.5" Sleeve width at hem 5" In good pre-loved condition.
