Just come back from the hospital where they ask you to strip down to bra and pants. I don't wear pants I wear knickers. Apart from the gentlemen here do you wear pants or knickers.
My Aussie friend and her family call them - duds - which my DC thought was hilarious when they initially heard it but then took it on board for the name they used.
Trying hard...., but no, I can't remember when I last had any conversation that may have included the words knickers or pants. As a child I wore knickers, I always checked that my daughters had clean knickers (or keks as we would say in Manchester) - but in all honesty I don't generally have reason to say anything about them at all. And I really have no preference as long as people understand what I mean if I have call to use either term.
Pants. Knickers are great big things made from lock knit cotton with elasticated legs and waist and space to keep your hanky up the leg (at least that is what our elocution teacher did)
I think knickers sounds coarse and I would find it out of place if I was asked to strip to my knickers at the doctor's. Couldn't they say "strip to your underwear"?
In German the word is "slip", too - most confusing. It's not as if, at my age, I "slip" them on. More like a hopping and rocking, grunting and puffing, till I'm there!
