I often wonder the same thing about myself, but honestly I think as you get older you get more refined and go for the classy styles rather than trendy - nothin wrong with that!
I totally know what you mean, and this HAS happened with clothes and things like that. But...I don't know... I mean when I was younger, I had every color bag and style and never thought about anything other than if I like it. Like, I LOVE the cerise speedy, but can't bring myself to buy one, because I just cannot see myself carrying a bag with cherries all over it.
I think I'm getting more timid in my choices and that can only be due to my age.....my advancing sucky age....
