I don't know your DIL's tastes...so its hard to say. How old is your DIL?
I personally wouldn't use that fabric for a purse, but my tastes lie more in solids/tonals/marbles and less with themes and novelty prints for something I'm going to carry around every day - I like batiks for purses. I love the fabric you chose for the liner, though! I'd be more likely to use that.
