OK, so where can I get good v-neck sweaters that fit well? I am in Britain (so I use the word 'sweater' solely on this forum and a raisther different word in real life) and know nothing about this garment, as I have never bought one. The last time I wore one was as part of my primary school uniform. I think I want v-neck. I am not sure about the various materials. What is the difference between merino, lambswool and cashmere and which is best? Where can I shop (online, perhaps?) to get these things? Thanks.
