This is a great light weight tank. true to size, but size up if you prefer a baggier fit, size down for a closer fit. your preference for fit should be your guide. (i prefer a closer fit, so i choose a xs, i am a 6-8 in tops) the arm holes are slim and high so you are completely covered in all sizes. excellent drape, the twist in the front is just perfect! looks great with jeans, print joggers, and even wide leg pants. i imagine it would be fantastic with a pencil skirt - denim perhaps. hope it
