They're everywhere you look on the highstreet and the catwalk, they're practical and reasonably priced and come in such a wide variety you could easily collect enough for every day of the week. Make room (you'll need it) for Icelandic jumpers and cardigans.

Last winter I was listening to a lot of Sigur Ros, which lead me to google Icelandic jumpers (or as they call them lopapeysa), to wear while listening to Sigur Ros, because that's not weird or pathetic. I even fancied moving to Iceland, where I'd have to wear these jumpers or literally risk death. So this was enough of an excuse to get my lopapeysa ordered. I was a little shocked at the price, I don't know what I expected, but apparently they are water proof and are actually warm enough to wear outside on their own, in Iceland. Perhaps a bit much for our British winters then. 

This obsession was resolved cheaply a week or so later when I discovered a neat lambswool jumper in H&M, which I wore to death. It wasn't incredibly warm, but it served well in the layers party. This year, you can't go in any clothing store without an abundant stock of Fairisle, which isn't absolutely amazing, finally, a WARM fashion statement!
