'Are you looking for a jumper?' should be accepted.
We also have a word джемпер :)
But yeah, report it, I think you are right
Hmm wait I googled светр and джемпер in images and it looks like светр is any kind of pullover but джемпер is some other sweater-like kind of clothes... Is it the same in English?
Thanks, I reported it to be safe. There may be slight differences of which I am unaware, but in general what is called a sweater in American English would be called a jumper in UK/Standard English.
In American English, a jumper is more like a full body outfit, typically associated with toddlers and small children.
