The way people from the UK call sweatshirts, long sleeved tops and sweaters "jumpers" and I always get disappointed when it's not more like a onesie or a baggy unitard.
Granted I don't think I could explain exactly what a "jumper" is, but I think it's supposed to have suspenders or straps or something and both a top and a bottom fused together. You know... for snow or "romping"
@llewelly@futurebird According to wiki-thingy, a jumper (US English) is a sun dress with a top under it. So, jumping out of a plane in one of those would be, uh – if it was voluminous enough, it could be your chute.
