I ordered this super cute half slip in a size XL after reading the reviews. I am a size 8 on the bottom, and a size medium or large up top, and in dresses. I read that this slip runs small so I went ahead and ordered the XL. It comes to right below my knee, which is absolutely perfect for my dresses that come a few inches above my knee....a bit too short for work or for church. But this half slip is adorable and I highly recommend it. You might remember to size up  about 2 sizes, like I did. I will be ordering this half slip in other colors, too! I hope this review helps someone!
