This is interesting! I've been under the impression that they are seriously on the way "out" as a "hot fashion trend." By that I mean that I'm not seeing the young fashion-forward celebs wearing them much any more.
But I do agree that there are a lot of brooch lovers out there who will always buy and wear brooches. I've met a lot of them! I love when people embrace their own style and don't feel they have to follow what the 20-something actresses in L.A. are wearing, so I definitely applaud that.
I've never been much of a brooch person myself, even during the recent fad - that is, I don't wear them as part of my everyday wardrobe. However I think a vintage or vintage-style brooch can make a nice accent to more formal wear. I especially like the idea of wearing one at the side of a sash or centered right in the middle instead of off to the side. We saw this a lot at the last Academy Awards - we'll see if they appear this year very soon!
(I remember Drew Barrymore wore one on her back. I just couldn't figure out how she could possibly sit back in a chair without hurting herself.)
