From St. John Sport by Marie Gray -- brown lamb leather, button front jacket with side slit pockets. Very soft & pliable. 
1 loose button (pictured). Still attached but you might want to anchor it a bit. Otherwise excellent condition - no rips or stains, lining intact.

See photos for measurements. Compare to a garment you own to assure good fit.
