I grabbed my typical size (8) and found it fit snug in the bust. the fabric has plenty of stretch, so the snugness was fine, especially because it meant there was no gaping along the neckline in the front. it's lowcut, but i didn't feel particularly exposed. i ended up not buying it because i don't think it fit my body right. the distance between the top of the shoulder and the bottom of the arm hole was too long for me - a significant portion of my bra was exposed at the bottom of the arm hole
