OMG THIS MATCH. I cannot wait.
(10) Bella Thorne vs. (14) Charli XCX
Honestly, I feel like these two would get along. At the very least, I think they would like to raid each other's closets.
(As ever, also, I point you to the archives, although in this case I think everything eligible is in the slideshow. Regardless: Here are Bella's; here are Charli's.)
