This fit as I expected. I am 5'7" and 124lbs, and wear 3 in juniors. I ordered a small and it was a perfect fit. It was snug enough without being too tight, I had enough room to move around in without feeling restricted. My biggest concern was ordering something with too much room since I'm am not the most graceful person in the chemistry lab I feared it would be big and loose. But, it fits perfect! Also the sleeves are quarter sleeves which is also great, because sleeves can be a problem in a chemistry lab.
