I have about 3 or 4 akemi & kin tops. i usually take a small. i think this one runs a bit bigger. the armholes are too deep and there is just too much fabric for me. (5'6" 125lbs) i am going to try to size down because i really like everything else about the top. orange is not my color but this has enough white to compensate. the pattern, button detail and fabric are all very nice.
