My dialect is a little mixed. I say trousers more often than pants, but I much prefer to refer to the trunk and the hood of my car than the boot and bonnet. I use vest and waist coat interchangeably.
In the UK the top item is a body warmer and the bottom a waistcoat. Tank tops sound like either part of a military vehicle or part of a heavy kilt. A vest is what we in the UK wear next to the skin under a shirt and put trunks in boots if we are not wearing them to go swimming after which we put pants on under our trousers. Not confusing at all.
