It is a great system if you are hard to fit. I am an exagerated "pear" and it works great for me. It is huge in the UK, Denmark where it originated in the 1930's!!!, Germany and such. It seems pricey but with your initial purchase you get about 200 patterns! Granted, some are childrens and some are men's, but very few. If you can get a basic skirt, top and pants to fit perfectly it is really all you need, from there the sky is the limit! Basic sewing knowledge is required though...not for a beginner sewist. Michelle
