the material is featherweight. you don't even know you are wearing it. I am 5' 6 1/2" and weigh 120. I ordered the medium originally, but reordered in the large. I thought the waste on the medium was a bit short. the size as far as the dress went didn't change much with length, and fit. I can't wait to wear this on my vacation. I kept the gunmetal and gave the chrysanthemum to my daughter. it wasn't me. She loved it. we wear the same size, so she basically has two closets! lucky girl!
