Lululemon Tank Size 6 but based on measurements this tank top fits like a size 4. Although this has the 6 size dot it appeared smaller and I am providing photos with measurements of the pit to pit and length. Please look at all the photos and make your decision based on the measurements. Imperfections can be seen in the front and back of the stitching. I have provided photos showing the imperfections.
