EUC Lululemon Ruched Racer Back Tank Top S…

Lululemon green pinstriped racer back tank top. The racer back has ruching. The tag and size sticker are gone. I believe it to be a size 6. In excellent used condition. Armpit to armpit measures approximately 13.5". I laid it on another size 6 I have and they match in size. No holes, rips or stains.
