This is Rarity from My Little Pony: Equestria Girls captured as a bunny girl.

Rarity is a character from the My Little Pony franchise and one of the main characters in My Little Pony: Friendship is Magic who appeared in Equestria Girls. She represents the element of generosity.

Rarity is the older sister of Sweetie Belle.
She has a different relationship with Spike than in the series: In the film, Rarity thinks Spike is a normal dog; however, once it is revealed that he isn’t, the relationship becomes similar to how it is in the series.
In the human world, Rarity has an eye for fashion like her pony counterpart and is usually seen with her bag filled with outfits.
She offered once to help with decorations for the school function, but Sunset Shimmer forged an email to her saying that all the positions were filled signed by Pinkie Pie and later Rarity found out that Pinkie had done all the decorating by herself causing a rift between the two, but when Twilight revealed this was the cause of Sunset Shimmer, they reconciled. Later on, she suggests to the Main 6 that they become real Canterlot Wondercolts whilst she showed them pony like headbands and tails to support Twilight for her campaign to become the Princess of the Fall Formal.
