I am 5'0, 103 lbs, measurements 34-26-36. I took an extra small (Asian label M), which I usually don't do, but I wanted an exact fit for this shirt, nothing loose. When it came, the first thing I noticed wasthrwas great feel of the material. When I tried it on, it work well for both a buttoned-up tucked-in look, and an open shirted with an inner look. Great fit, just use the size chart for the fit you're looking for, loose or snug.
