I have this tank in many colors. I love them because I know they will all fit exactly the same, I can add fun colors to my wardrobe. I'm very thin and small framed, so I wear the XS. I, personally, do not put them in the dryer. They are 100% cotton, which is great...but they are JUST the right fit when air dried...I tried the small and threw it in the dryer and it was still too big! SO, I love this tank. I advise you getting as many colors as possible! I think I have pink, purple, charcoal, and grass in this particular tank.
