Lululemon Coral women's tank top, no size tag so see measurements below but I believe it is a size 6.  It is made of a tech type material and is very breathable, lots of ventilation, i believe it is meant for running. Cropped style.  Shirt has a tiny repair near the bottom where a few stitches were put in (see closeup) and also there are some darker marks on the side in 3 small spots- they are not very noticeable but see the closeup.  Stored in a smoke-free environment.
