I love the this outfit. I'm 5'5" 160lbs and bought a size large. The quality is topnotch and the color scheme (blue tie dye) is pretty! I have washed the outfit in cold water and threw into a dryer on the low setting. It came out perfect...no shrinkage. The top is very loose which is great for sleeping and lounging. The bottoms have about a 2" inseam. The waist expands 3-4 inches. The drawstring is for decorative purposes. It does not make the waist have a tighter fit. You can wear for sleeping or for a casual outfit.

The fabric is sooooo soft, durable, excellent quality, definitely not thin, and not too thick. It feels so good against my skin, and looks even better in person than in the photos!! I wanted it to be a little loose and comfy like in the photos. I'm 5'2" and weigh 140lbs, and I ordered a size Medium to match the fit in the photos. This has become my favorite set - even comfortable during the summer (I live in Florida). I'm buying more sets as we speak!
