My tanks comes in a pack of 2 and are currently 40% off with an on listing coupon, under $15. You can also get 1 tank for Under $11 (but I think they are so cute, that you got to snag a 2 pack). Please note, the coupon can be changed or removed at any time. I am wearing a size XS and they are fitted and stretchy. I say go true to size. Click below to shop.
