I ignored the seller's sizes and went based on the reviews and got a Medium. I am 147lbs, 5'5", 39" hips and 32" waist. The medium was a little loose despite this, so I am very happy I didn't go with the seller's listed sizes. However, this thing is LONG. There would have been fabric under my shoes every step wearing flats, and it would just be a dirty mess. I was hoping to return for a small, but the seller's sizes say it's the same length.

Also, the fabric is the type that will pill up immediately in the dryer. This is an air dry or delicate dry with no heat type fabric.
