I really love the idea behind this. however, the fit doesn't work for me. i'm usually a s or xs in retailer tops, and i often go with xs for sleeveless tops. this one runs small though - the xs was a bit too small on me based on length and width. the neckline was very high (higher than it looks in the model photo) and the armholes were too big. so i don't think sizing up would improve matters much due to the armhole issue. the other criticism is that the front is not lined.
