Since many of us are having fun with the Chanel look, I thought I'd post a link to a brooch I found a while ago. Quite Chanel-esque me thinks.

There's also a zipper brooch on the site, a bit similar to the fab one Michelle has.

They have loads of brooches, actually, granted not all equally fab, but maybe worth a look anyway.
