Jennifer George Vintage Womens Suit, Dress w/ a suit jacket. Size 6 fits like 4

Vintage Jennifer George Olive moss green dress with matching jacket. Midi length sleeveless dress with darts to make flattering fit. Cute knit women's suit. Jacket has two large pockets and 4 wooden buttons. The suit is a size 6 but fits like a 4. Probably shouldn't include the pics of me modeling it because it is too small on me but can use it a point of reference. I'm 5'8" and 130 lbs. (I also have very long arms). I wear a size 6 most of the time. Open to offers!
