I'd like to use the correct word for a fanfiction. In Germany (or at least in my childhood days in Eastern Germany) we called that a Westover and only once I learned/learnt English I realized that this is exactly what it is doing - a Vest that you put over a shirt. I just googled and found that another word for it is Pullunder which again is something you pull on under your jacket to keep warm.
When I put that into the dictionary, I get "Slipover". Which sounds - hm. Never heard it before. So please, enlighten me, what is the name of that woolen thing without sleeves and buttons which you just pull over your head? Are people even still wearing this?
Personally, I adore my fleece cardigans. Never go anywhere without one.
