Gift ideas for girlfriend

My girlfriend's birthday is around 20th of this month and i cant figure out what to get her other than a dress. But since i got her a dress last year i want to get her something else. I also made her a bouquet bouquet with ribbon roses before that and got a dress before last year. I have no idea what girls like and have no female friend to ask about it. It would be great if yall could suggest me something. My budget is kinda tight at the moment but im willing to spend 1-2k.
