NWOT Forever 21 cropped sheer lace trimmed shrug

NWOT, I wasn’t sure what to call this; it could be worn as a top or over a tank top or dress…lingerie maybe?? 90% polyester 10% spandex, delicate light fabric. Lace trim, smocking at mid-upper arm. Would be most flattering for someone with slimmer arms and size small or medium.
