Very, very impressed with this dress.  It is a smooth stretchy high quality, fairly lightweight fabric that drapes well.  Ran through the washer and drip dried with no issues.  The skirt has a nice flare to it, this is excellent basic dress that can be dressed up or down, is very comfortable to wear and just generally very well made.  At the time of this writing the cost is not listed so I cannot speak to the value.  Sub fifty would be quite reasonable for this dress.
Size medium fits a woman who usually wears a size 34 B bra ans is 5ft 7, 145 lbs very well.  Hits just above the knee.
