Lululemon Flow & Go Size Medium? Tank Top

Good condition, except for some very minor marks seen in the photos and a minor pull. No size tag, but my guess is size medium based on the measurements and how it fit on the mannequin. Please be aware measurements might be off; due to the design of the tank top it was somewhat difficult to measure. Ptp 16 inches stretches to 20 Waist 15 inches stretches to 19 Length give or take 24 inches
