I say...
Dragonfly 2 is a great little knife. But with that you may just have to keep sizing up.
So I say:
Spyderco Delica 4 Purple FFG - Very nice knife.
But for around the same price you can get the same handle material, same lock, and a better steel...
So ultimately I would get her the Spyderco Native in pink.
My mom loves my delica she thinks it's cute and nice. But when I had my native, she was crazy about that little guy lol.
The native fits the hand like a glove, better steel, holds a hell of an edge, and you can use it for EVERYTHING.
