Sparkle & Fade Extreme Tback Halter Top

Sparkle & Fade Extreme Tback Tank Top Silky, breezy tank top from sparkle & fade with a halter neckline and an open, deep t-back. cut in a drapey silhouette with button closure at the top. GREAT CONDITION. Can't find the size but would be a Small or Medium. I am an XS now and it fits but I would definitely need bigger a chest area in order to fill out the top of the shirt to prevent inappropriate exposure when bending over.
