Depiction in equestria girls

Human version of Rarity.

In My Little Pony Equestria Girls, Rarity's human counterpart gives Twilight a disguise to make her unrecognizable and says that it's too bad they'll also need a disguise for Spike, because she finds him "so adorable." Later, in the human world's Sugarcube Corner, she lets Spike sleep on her legs and pets his back. She warns Twilight to stay away from Flash Sentry, Sunset Shimmer's ex-boyfriend. Rarity's idea of rallying the students by encouraging them to wear the Canterlot Wondercolts' headbands, tie-on tails, and jerseys is a success. Rarity also says she hasn't sold any of the Canterlot Wondercolts' paraphernalia in ages. 
When the students find out that Spike can talk, he incredulously asks if a talking dog is the weirdest thing they've seen that night. Rarity says she for one thinks he is adorable. She picks him up and scratches him behind his ears.
According to a crew member, in an early draft of the movie, Rarity was the girl who unsuccessfully ran for Princess of the Spring Fling against Sunset Shimmer, but the final draft of the movie did not reveal this.^[5] The crew member also stated that "a couple of lines in the movie" still imply it. In the movie, Fluttershy mentions the unsuccessful candidate for Princess of the Spring Fling when she advises Twilight against running for Fall Formal Princess. Later in the movie, Rarity says she expects "some sort of apology for last spring's debacle."
