Yes, I say something from the azur collection.. since she has quite a variety already! So I say keep the variety and buy something azur! Wow 14!! nice collection for a 14 year old, i have to say!! tell her well done from me.
i saw a damier speedy 25 on a girl around that age at the mall a couple months ago. i thought it was great! classy but age appropriate. like others said, the azure might be a nice twist as well.
