Replying to Oakley one pieces yo!

ok, so im hoping to get my hands on an oakley medic one piece for the season, but i got some sizing issues. im 6'1", 190lbs or so, but thin. i got a sz l oekly uniform puffy and xl sector pants. i sag the pants a good bit when i wear em to get em to fit how i like. so my question is, should i get a sz xl or xxl one piece? i want it to be big, but not look like i weigh 1400 lbs cos its super loose in the top. basically i want something thatll fit me right up top, and pretty baggy legs. any input would be super helpful. thanks fellahs.
