J.Crew Vintage Cotton Silk-Back Tee in Light Blue

"It looks and feels like your favorite well-worn T-shirt. (We created the fabric back in 2004 to do just that.) It's supersoft and featherweight, so treat it like you would your lingerie. Paired with a silk back panel, it's a T-shirt worthy of a night out." Back and hem: 100% silk. The rest: 100% cotton. The color is a very light baby blue/periwinkle blue. Condition is gently worn - there is evidence of it having been washed a few times; you can tell on the cotton.
