Etienne Aigner Vintage Genuine Leather Jacket

Great condition, just wrinkled from being stored away in the box. Worn once. One small scuff as is shown on the picture. The tag says size 10 but I'm 5'6 140lbs 36D and it is very tight on my chest. I typically wear size small and I think it is US size 4-6 . Etienne Aigner brand.
