Silky Sleeveless "Shell" Top

Sleek design, "wrinkled" look is intentional/type of fabric. Back of shirt would make you think at first glance it is inside out, but zipper is on the outside on purpose. Very small snag on the front (see picture). Size is technically a large but fits more like a medium. Flat measurements in inches: underarm to underarm = 20 underarm to bottom hem = 16 shoulder to bottom hem = 25
