If its got the wire, the wire has worn down, or may be out of place! >< it might be too small too :P you need to get yourself a new bra . :)
It is the underwire, I just would like to know cause whenever I move, it squeaks and it's starting to get embarrassing ...
Or, the under wire is made of plastic... that would most likely be the cause of your squeaky bra. :]
Sometimes if I buy a cheap bra from walmart the underwire is plastic and makes this squeakey sound.
ehrm... is it a strapless one? it might be the uhm rubber stuff rubbing ur skin?
Perhaps it's from the metal under wire rubbing against the fabric?
usaully thats just the underwire in the bra.
I think you need to take it off!
This one isn't cheap though :S
