Always loved them, covet them and have a few here, but I notice that whenever winter comes around I don't seem to wear them much. They are ok if chunky, without a coat, but I often struggle to get them neatly under coats.
If there is any chunkiness at all then coats fit horribly over them, especially if sleeves are wide, too long or dropped shoulder.
So I realised only fine, thinner knits that sit close to the body work well under a coat. Not rocket science but frustrating as most knitwear right now is boxy, thick or wide sleeved.
Is there an alternative to keeping warm? I have some nice coats and love wearing them but my knits from the likes of Toast and Finisterre are too ungainly to go under them, and whenever I wear cashmere the slightest thing destroys them, no matter the price point. So maybe they're great for days when you dont need a coat and it isn't raining, or if you are happy to wear a bloody massive coat 
I suppose i need something thin that is warm. Does anyone else find this is the case? I also get warm too easily thanks to meno now so being ever so slightly cooler is preferable!
