I'm so fed up of constantly trying to find good quality knitwear in a petite length. A few months ago I went to a personal shopper who couldn't find me one single thing that fitted, but she did suggest I could get stuff from Hobbs and have it shortened. Can you really do this with knitwear? If you needed to remove about 3-4 inches, wouldn't the knit start unravelling? And even if it could be done, it sounds like a specialist thing so presumably it would be really expensive?
