Sezane Chlo Shirt in Black guipure, size 4 (36 in French sizing). This lovely button-up blouse features a high collar with ruffles along the placket and collar. The black "guipure" fabric is 82% organic cotton, 18% Recycled polyester. It has a lace-like effect -- the shirt is sheer throughout, and you can see through to skin/whatever you choose to wear underneath (see product photo for what that looks like). I wore this only a handful of times, it is in very good condition. I find it fits mostly true to size, but is a little bit shorter than some other Sezane tops (though I am 5'10).
