I ordered the xs p and xxs p in the black one. i thought this would be a fairly classic piece to wear any season (cold offices in the summer, southern california in the winter). the xxs p was a bit better fitted, not too small, but the xs p was ok too, if you prefer a baggier look, so based on that i call it large as i would usually purchase the xs p not xxsp. (115 lbs, 30 dd, 26.5in waist, muscular arms)

the material is airy and light, but i am a little worried about wrinkling, we shall see.
