This is a vintage (1990's) Donna Karan Brown Double Breasted Suit in a Size 6
The jacket is beautifully made and really stunning in real life. It has a luxurios 100% silk lining. It is a stand alone piece.
The skirt is eqaully well made with the same lining. The only problem with the skirt is that it has one hole on the back waist that I show in the last picture above. I also noticed a couple of tiny moth holes or something. I tried to show them in the second to last photo.
