I would consider the PM classic and the GM "almost classic." I don't think either of these bags are going to go out of style - they're just so pretty. 31 years old is just a youngster! (I'm 50 which is why I'm not scooping this right up). I'm still thinking about the PM though, although I carry so much and tend to be a die hard speedy and alma person. I don't think you can go wrong though, especially as young as you are. This is a bag I can see you carrying well into your forties. I saw it in the boutique the other day and it's really really cute.l
