By Gryphon New York, this elegant black duster is 90% cotton with 10% metallic thread woven throughout the fabric to give it a silvery shimmer and a crinkled appearance. A pipeline of silver beads swirl along the trim and the pockets. Front snaps are hidden behind the lapel.

The tag says size L, I think it's more of a medium.  Consider the measurements before you buy, specifically the sleeve length.

Sleeve length from shoulder to wrist: 21 inches.

Sleeve length from arm pit to wrist: 15 inches.
