I LOVE the look of this jacket so much that I bought 5 colors(green on Amazon). The longer length is flattering, and the fabric is perfectly soft and offers just enough for a little lightweight extra coverage. Though I usually struggle finding a good fit between XS and S,  after reading reviews I decided to go for XS, and am glad I did!  The jacket has elastic cinchers inside at both the waist and hem, to help tailor the fit a bit more. The pockets are lined with a mesh material on the inside of the jacket. The only caveat is that if you tend to be petite (in the XS size), but have an ample chest, this may not fit there....the jacket seems to be made to fit more perfect/balanced body pre-portions.

HEADS UP:  I called Columbia.com searching for other colors, and they told me the 'only' few colors they offer in this style, and the names given(of colors), (which don't correspond with the ones sold on Amazon). They have warned me of 'fakes out there'. I suspect this green one, as the waist elastic cinchers have loose, raw, tied ends, which Columbia never finishes their jackets that way. I have 8 'official' Columbia windbreaker-type jackets in all, including the 4 I of this style which I just purchased, and sure enough, the elastic cinchers are not finished that way. I haven't had this {Amazon -purchased} one long enough to more closely inspect for substandard details, but still, I like the look of the green jacket and hope that it will hold up.
