This sweater is well made, very soft and comfortable. It runs a bit big through the torso, probably due to the Dolman style. At the forearms and around the hips, the sweater is nicely snug. I am 5'2", weigh 128 and purchased a Small. The S fits comfortably; however, it there had been an XS I may have bought it to see if it was a slimmer fit. If you are a true XS person this sweater may not be the right one for you. However loose-fitting the style, having the deep-V back is a very sexy touch. The front neckline is also a V and on me, even with my 34Ds, the sweater comes much lower than what is depicted in the Amazon photo  low enough to show a hint of cleavage and drop off a shoulder from time to time. Almost perfect; great for the price!
