Gift suggestion for a very close female friend which may be my girlfriend soon, or may be not.

Hi everyone, I'm in a tricky situation. I know this girl since 6 months and we are now super close one to each other. Since months we are talking about our respective gifts, but I don't have any idea.As stupid as I am, I told her that I was super good for birthday's present. She loves to dress well and likes red, so I was thinking of that, but It may get weird since she's not (yet?) my girlfriend.Basically I need a gift for a girl of 18 years old. She's from Japan (and really proud of it), loves chocolate and she's a hard worker. via /r/Gifts http://bit.ly/2k5XOIL
