I had been looking for a jacket like this for months, but haven't found the right style, until i saw this one! luckily it was on sale. i am 5'10, weigh ca. 143lb's and i usually wear a size small in all retailer tops. tried on medium, but it was too big in the bust area., then i tried on the small and it fits great! the sleeves are long enough too, but it is hard to move my arms up to reach something, so i just have to avoid that. :) i have gotten a lot of compliments for it.
