All of them!
Actually if I had to pick a fave I'd totally vote for the green album/current look. I also love the long haired Pinkerton look...
However I LOVE this look too.. a lot.. but I love the black glasses... they're iconic:
I liked it when Rivers dressed up with the suit and tie and glasses after the summer of 2002 with the Keep Fishin' video and the rest of the Maladroit tour. Plus I like the Blue album look with Rivers and the short hair.
