I'm a HUGE fan of Columbia quick-dry type shirts. Because I spend so much time outdoors, my closet is full of them.  Columbia makes a wide range of blouse-type shirts that are ideal for outdoor activities.  Unfortunately, the sizing between styles is not consistent within the brand.

On the issue of sizing, I am 5' 7" and weigh an athletic 145 pounds.  Bust is 36, waist is 29 and hips are 38.  I ordered this shirt in a medium.  It was too big.  I think the size small would be much better but I'm not going to re-order, as I already know that my favorite Columbia shirt is the Silver Ridge Long Sleeve (this is the LITE version of that shirt and yes, it is thinner).

Like the thicker version of this shirt, this one too, tapers in at the waist very nicely.  It's super flattering for a woman with a "girlish" figure (small waist).  There are two breast pockets which tab closed with Velcro.  And there are small vents on the back of the shirt over the shoulder blades.  it's a lovely shirt all things considered and the fabric has a nice slight stretch to it.  So although I don't plan to keep it, other then the sizing, it's a very nice piece of outdoor clothing that would go from trail to town seamlessly.  It is also ideal for travel, as it will dry quickly, although I think this fabric is more prone to wrinkling then the non-lite version of this shirt.
