I was reading about these support [[http://www.j-sainsbury.co.uk/media/latest-stories/2012/20120404-shape-up-for-summer-with-miracle-jeans-from-sainsburys/ jeans]]. Has anybody tried them? You can't see what they look like from the back and they don't have an online clothing section. Sainsburys have 25% off in store so was wondering if they were worth trying. Anyone?
