Thanks, Artemis!
Vicki, when I was a kid and we really used the word "jumper", it referred to a long-sleeved woolly or synthetic-material shirt always or usually worn over another, thinner, short- or long-sleeved shirt. The jumper usually wasn't very loose, and it was never buttoned-up like a cardigan. The shirt-under-the-jumper was usually called a "blus" (blouse).
