I purchased a medium. i am 5'6" 140 lbs and it fit perfectly. the navy is pretty dark, almost black. the fabric is very soft. the cut is more form fitting in the top and then comes out to an a line. it is not as bulky as some swing dresses. in the photo it almost looks like a handkerchief hem, but in real life it is less pronounced. i have no negatives. i would consider getting a second pattern if it goes on sale.
