Heavy in weight but not uncomfortable to wear because it's fully lined and has an easy fit that skims without looking like a potato sack! fits a little large but mainly tts. if you're between sizes, then i would size down, unless you're very blessed from the waist down. i am a m/l on top and s/m on bottom and bought the medium. it's a relaxed dress (like a shift suppose to be) that i can wear a turtleneck under without feeling stuffed.
