lululemon tank lot size 4 blue and black

There’s no size dot or ripout tag on either tank. The blue tank has a small hole to the front, material is very soft and slinky, and does have some wash wear and mild pilling. Blue tank measurements from the lower side of the arm opening: 13.5 inches Length: 23 inches, a bit longer in the back The black tank has a mesh shelf bra which does not allow for bra inserts and it is not padded. Black tank measurements Pit to pit: 13 inches Length from top of bodice to bottom front hem: 18 inches I am guessing this tank is also a size 4. This tank may be vintage as per the style, really doesn’t have any flaws.
