Lavender gray trench with feminine details

Beautiful piece picked up from a NYC sample sale. The collar, buttons and lining make this piece unlike any other. The back pleats are feminine and flattering. There is a missing button, but I never wore it buttoned, I tied the belt. The size says XL, but I am a size 2 so I am going to list as M. The color is also really unique. Would look add an entire new look to jeans and a white tee or I often paired it with a mini dress under. Cotton material...light, not for warmth.
