If you were to poll a large swathe of people as to whether cashmere is over or underrated, I really have no clue what the consensus would be; but I think cashmere is underrated. I was not a sweater person for quite a while but have become one and culled a pretty decent collection of knitwear that I like to pull from when I want to dress to impress. Anyway, cotton sweaters are a bit too pedestrian, merino a tad too formal and while I love shetland, it can be a itchy and requires intentional layering. Cashmere balances all of the best elements of the aforementioned knits and feels delightful on the skin. I recommend you pick one up and not from Uniqlo (or insert other high street brand) - I like Ralph, Loro Piana, Malo. How pompous do I sound?
