Love this top! got it in white for a recent trip to paris - felt chic and cool during a bit of a spring heat wave in the city of lights. it runs somewhat small - i'm 5'7, 128 lbs, broad shoulders, and got the 6. my usual 4 fit but was a little snug. i would recommend going up in size in this style. the 6 looked better because it is supposed to be a boxy, swingy top.
