Portrait Lego

It’s my nieces 19th birthday soon and she has really started to like Lego. So I want to buy her a set. Idk what sets she got, so I asked her in a sneaky ish way to show her set. Told her I want to get into Lego, and if I could see the sets she got. Then she showed me and described them to me, and also told me the concept of the one she wants. This is the transcript for how she described it :

“But I really wanna get the you know the ones where it's like you can stick them on your wall, cause they're kind of like portraits and I know how to explain it but I really want those ones”

Any recommendations of what I could get her, she’s quite the girly girl. Thank you in advance.
