Love this dress!! I ordered a 4x according to the chart measurements and it fit nice.  I am normally a size 18/20. 215 lbs. 57. It hit me right below the knees. My only problem is that I have a small chest, 42B. So I always have extra room on the top when ordering clothes. I also purchased a petticoat for underneath. Made all the difference in the world! It gave the dress a little more poof! You can certainly wear the dress without one too. I think I am going to order another dress and try it in a 3x to see how it fits. I plan on keeping this one too! Do not hesitate to buy this! Very well made! Youll love it!
