Yeah, I love that little toothy grin of hers, like she was genuinely having fun with modelling (at least in those early days). In some shots I think she looks older than 17, but the last ones she looks like a fun loving teen which is really sweet, and visual representation perhaps of all the changes going on to the youth of the 60s. I guess she was what Vreeland would have called a Youthquaker too.
