ROCK BOTTOM! Lululemon Workout Tank Top with Built-in Shelf Bra, Maybe Small?

Army green Lululemon athletica workout tank with mesh racerback. The print features the Lululemon iconic logo. Gently preowned in good condition. There is minor pilling inside the bra cups and one small ink pen mark on front hem as shown in last photo. Please pay close attention to flat measurements. There is no size dot but I estimate it to be a Small.
