Is my girlfriend naive because she doesn’t mind the price of the gift I give her?

I know most of grown up women like expensive things like branded material things, but my girlfriend (26 years old) says she doesn’t mind the price of the gifts I give her, she says she even loves it if it’s just a cheap candy. Is she naive because grown up women should have “standards” when it comes to material things?
