I say to give them a try if you think you'd like them. I've seen some pairs at Anthro too; they're definitely getting more popular. I have been tempted, but they are not my style, so I don't bite.
I don't know if they look too young because I don't remember them the first time around, although I am older than you. I must have missed that trend!
I have found that with some items I experiment with where I am unsure of the youthful factor, I oftentimes am able to style them in such a way as to make them look more age appropriate. Sometimes it takes a while to hit on the right combination. And then there are other pieces where I feel less and less OK in them as time goes on, because they seem to feel more and more youthful! But you can't always tell up front.
