The Satin Princess Cinch has lacing in the back which will allow further customization of fit, and the hook and eye closures in the front make it easier to get on and off.
The satin princess cincher looks like you can do a lot more with it, it looks really sturdy too. I love cinchers, I have one and although I haven't really gotten to wear it, the times when I did have it on it gave me amazing shape!
