Love the fit of the Prana dresses.  Bought the dragonfly color and it is such a pretty blue.  I wear a medium. I am 5'8", 135lbs, small chested, and this dress is super comfy with the built in bra. Nice to not have to wear one.  It easily is worn for everyday running around, and nice enough to wear out in the evening.  The length is above the knee, but respectably so, not short short, a nice summer dress.  Lots of compliments!
