What to gift my best friend?

So my best friend’s birthday is coming and I don’t know what exactly to gift her. She’s a girly girl so I might get some cosmetics , she likes reading but we’ve gifted each other books today (world books and roses day) so I’m not sure if I want to give her another book.

I need y’all to suggest me some gifts for her (17 F) even handmade ones would be fine but yeah I’d appreciate your help<3
