Lululemon Athletica white /grey halter neck tunic/dress. Size US 6

At 32” in length this lululemon tunic could be worn as a dress, but I always wore it with leggings. The shelf bra has openings to insert bra cups as an option but it did not come with bra cups. Halter neck and empire waist. Very gently worn. No pilling. There is a small mark on the front just below the empire waist seam ( see photos) No care tags but I washed on a delicate cycle and hang to dry with no problems. No size tags but I believe it s a size US 6- please see photos for measurements.
