So I'm 5ft 2in, about 157cm tall and during exercise my weight varies between 110 and 135 pounds. . The shirt is stretchy, almost like jersey but not quite. This is fantastic as the shirt fits my entire weight range well. It's more relaxed with less weight, yet flexible enough to handle 20-30 pounds. Pack.Material is a 50/50 poly-cotton blend, so take care when washing. IT WILL SHRINK WITH CONTINUOUS USING OF HOT WATER. Otherwise the shirts are designed to fit while maintaining a decent length, this is a casual sport polo shirt so I would not recommend refilling it. All in all a good buy if you get the idea You get, and feel, nice and thinner than most would be comfortable with, but you can always add more layers.
