Lululemon Cool Racerback Tank Gray Size 4 / 6

This Lululemon Cool Racerback tank has one flaw which is reflected in the price. There is discoloration around the upper back neck area and has been shown in the last 4 photos. There are no other flaws. This tank is a light gray color and reads slightly pinky purplish with contrast yellow stitching on the interior. There is no marked size so please check below measurements to insure best fit. Based on the bust size, I think this is between a size 4-6. D52 Size: 4-6 Bust flat: 13.5” Length: 29”
