I'm after navy cardigans for my girls. I'm fed up with the 100% cotton ones as they seem to lose colour and shape quickly and look grotty (even the expensive ones). However dd has one wool mix jumper she's had for a year now and it still looks good as new. I'd like to find some decent cardigans. They do have them at Marks and Spencer but they have a bad review saying the quality is not great so am now looking elsewhere. Any ideas? Looking for aged 4 and aged 6-7 ish.
