Measurements are approximate, taken with the garment laid flat. Shoulder width: 37.5cm Sleeve length: 56cm Width: 49cm Length from neck point to waist: 38.5cm Waist: 42cm I chose size L, but I think it would also fit a Japanese size M for mature women. I sewed it carefully, but it's handmade by an amateur. Thank you. It will be folded and sent via Nekopos. Please forgive any wrinkles.
