Vintage 90's J.crew silk slip dress aprox s/m

Vintage jcrew slip strappy lingerie style dress, no size material tag but I am positive the dress is 100% silk. Very pale blue with beige. Straps not adjustable. Paisley like floral print. Perfect for layering. I would say fits around S/M. Relaxed S to a more fitted M depending on the look you wish to have. I am between sizes S/M for reference. Underarm t to underarm is 18 and about 46 inches long with straps. Good vintage condition, no flaws to note.
