Bought this shirt to match a North Face run skirt I bought at the same time. I'm 5'6", 140lb, 34 in chest and 28 inch waist. I ordered a medium. The fit is odd. Tight through the shoulders and too big though the torso. The cut is boxy and not at all flattering. The fabric is "sticky" meaning it sticks to my sports bra and bunches up around the chest, at least until both are saturated with sweat, then it hangs o.k. This along with the run skirt made my first North Face purchase and I have to say I am unimpressed with the brand and even less impressed with the quality for the asking price. Back to my old faithful Mountain Hardware!
