CALVIN KLEIN Black Thin Silk/Cashmere Sweater

Super gorgeous Calvin Klein light weight fine weave 55% silk 45% cashmere sweater. Perfect for cool summer evenings, spring and fall. Runs small. I have two sizes, small and medium. I'm 5'8" and 126 and the small is too small and the medium fits tight. I personally like looser items so perhaps a preference thing.
