I got this slip dress to wear under a crochet dress I made.  I was going to make a slip but could not find fabric the color I wanted. I got this in the cocoa color which is a nice neutral pale brown sort of like coffee with cream. For reference I am 5'6" and weigh about 114, 32/24/37 and I got this in the Medium. I didn't want it super tight or baggy either. The medium fits through the bustline, is a little loose through the waist and is pretty snug over the hips (a little snugger than I wanted, but it is workable under the dress). It is a little loose under the arms, but not anything major and you can't tell under the dress I wear it with.  It washed nicely but looked like it was very twisted at first, the side seam was twisted toward the front, however after it dried completely it straightened out again. The fabric is soft and stretchy. This fell below my knee, pretty much like on the model, but I wanted it shorter so I shortened it to above the knee.
