I have heard the term 'wife-beater' used on shows, so I'm pleased you've cleared that up for me Iolanthe!! It makes sense in the context too.
I was watching 'The West Wing' last night and they used the word 'button' for what we would call a 'badge'. This was in the context of showing support for an election campaign. Do you still use the word 'button' as we do, as a clothing-fastening method, for want of a better description?! For example, at the top of jeans or on a cardigan (did we establish whether you use that word?!)? I think you do, but I'm not sure I know anymore!!
I can tell you, all the confusion over clothing is very problematic when trying to write nfic!!!
