It doesn't seem dated to me at all. I put it in the same calibur as Sara(h) or
Jessica: names that never seem to go away, but aren't trendy. Certainly not trashy or tacky, just very common. I have 4 Michelles on my Facebook friend list (one I went to high school with), and one
Michele. I don't really know any Michelles that are younger than me, the ones I know tend to be born sometime in the 70s or 80s.
I don't think it's "ready for a comeback" in that I still think it's "around". Sure, it's not the next
Isabella, but it's up there in popularity.
