I absolutely love the hot shorts. I have made these multiple times. However I have recently noticed that a few of my dancers have complained about the tightness around the leg area, so I have been having to go up a size in the legs.
I always go by waist and hip measurements so I know I am not off with the sizing. I think if they are a very active person you are sewing these for I would go up a size in the leg area. The waist size is spot on though.
