I made the back narrower than the front so it actually fits. Taking my measurements and custom fitting really makes a huge difference when you are not Miss Average (and who is?). I can recommend it. This is my first attempt with no pattern that’s why I went with something with all straight lines and ribbing to give the fit. It was a great learning experience.
