This is a Lululemon long sleeve top. My mom bought this top, cut out the tags, wore once, and got rid of it. Due to the tags being cut out, it is either a size 4 or 6, so definitely a size small, but I am not positive the exact size (so, I included measurements in the photos.) It is in perfect like new condition, but due to not knowing the exact size even with measurements, I am listing low. It is a sort of an orange red.
