i LOVE this dress. I bought it to wear during an engagement photo session, in the Dusty Rose color which I see is no longer available. It is such a pretty color and I definitely recommend it if it is an option in other dresses. Exactly what you'd expect with a dusty rose; a warm but muted pink.
I'm 6', 165 lbs and the medium fit me just right. I bought a large as well, but it was slightly too big and i didn't want a baggy look. The skirt laid on the ground about 2 inches, even with my height and flat sandals on.
It's a kind of crepe fabric, and is slightly sheer. Knowing I was going to be in bright sunlight I wore a skirt slip, but indoors or at night it wouldn't be necessary.
