We never used pants for trousers or wind cheater for anorak (although I think this is an Australian term) my friend still uses wireless but I don't and we never used drawers for knickers- now I call them pants!
We never used the word pants for trousers either although I believe Americans do.
Interesting that you say wind cheater is an Australian term, one of my grandparents grew up in New Zealand so maybe they handed the term down to my parents.
