Good list. Some more for you (including some obvious ones?)

Gown
Jockeys
Shorts
Sou'wester
Spats
Sweater

And just so we get the originals right:

mac = Mackintosh

wellies = Wellingtons = gumboots

As some of the others have said, some of the words are completely new to me - and I've love to discover the definitions or usages.

And yes, in Bombay it was common (in boy circles) to refer to bras as 'over the shoulder boulder holders', though we wouldn't mention it to girls (get our faces slapped and out mothers called, that would).
