Lululemon scoop floral tank

Purchased second hand from a local shop…no size tag but pretty sure it is a 4….I wear a 4 and this fits like all my other LLL. Unfortunately I missed the deadline to return this to the store…not my style. Seems to be in great used condition. A green blemish on the back/bottom area near the LLL silver logo (6th pic). Seams and stitching all intact.
