I live in London, and I'm looking to buy some wool sweaters for £30 - £70 each ($50 - $100). Something thick and durable - not cashmere - that I can wear without a jacket, such as a fisherman's, cable knit, bird's eye, fair isle, shetland, as long as it's not a v-neck. (I am following Put This On's advice from here and here) I am perfectly willing to wait for sales, or look in thrift shops, or look on eBay, but I am pretty clueless about which brands or what features to...
