Size 1X . It s fit more like a 2X . If your a 1X with a bigger chest , it would definitely work . I m a 1X but on me , it was super loose in the chest area . Right now they are sold out so I can t even return for a smaller size I paid $10 plus Shipping / Taxes . The top itself is comfortable, soft , light weight , stretchable and has adjustable straps . It came with extra buttons also .
