Lululemon Sculpt Tank- cutout back Royal blue color I think it is a size 12 or 14 (no size dot on these) but please see measurements - pit to pit 18” - shoulder to bottom of front 24.5” - shoulder to bottom of back 28” Gently used - no visible signs of wear that I can find (Not mesh like the photos on the model, but this is as close to the correct tank as I could find, but shows correct shape of cutout)
