My sons loved receiving gift cards and money.

I always get a bag. I got a niece a nice black backpack that I would wear. I think it was Calvin Klein or something. I was about five years ago. It was her first grown up bag.

A messenger bag is super useful:

Or for something a little different, the seatbelt bag:

What's an appropriate gift for a female high school graduate whose one parent is a close friend/work colleague? Not on the high schook scene yet so unsure of what's typical or what that age is into these days.
