Anine Bing April Tank Top in black. The size tag is cut out. I believe it is a size Small or XS. Slim fit, stretchy rib knit. Lying flat I measured the chest armpit-to-armpit at about 12.5" across. Approx. 20" long. "The April Tank is a great layering piece, made from a breathable, extra-comfy ribbed cotton material. We love the scoop neck detail. Pair the April back to jeans for a classic option or layer her under your favorite blazer for the most comfortably chic look. 95% Organic Cotton, 5% Spandex"
