*Rarity is a female human, a student from Canterlot High School and a keytarist for the Rainbooms. She is one of the main characters in My Little Pony Equestria Girls. She represents the element of generosity.
Rarity has white skin, long purple curled hair with three cut-out blue shaped diamonds for a hair clip, blue eyes, sky-blue eye shadow with long black lashes, and roving purple eyebrows. She has yellow and gold bracelets around her wrists, and since The Legend of Everfree, she wears a purple necklace with a neon purple geode pendant and a single diamond on it around her neck.
She previously wore a pale blue elbow-sleeved shirt, a purple skirt with her pony counterpart's cutie mark, a darker purple (or sometimes black) belt with two blue buckles, and purple boots in a high wedge heel, which lavender tops are covered with a single diamond.
Like her pony counterpart, Rarity is very beautiful & generous and has a keen eye for fashion. She disguises Twilight to hide her from the CHS students' ridicule, and she comes up with the idea of handing out pony ears and tails. Rarity also likes doting on the dragon-turned-puppy Spike, finding him "so adorable" and letting him sleep in her lap at the Sweet Shoppe.
Rarity's generosity and love for fashion carry over into the second and third films as well. In Rainbow Rocks, she greatly concerns herself with making a good stage impression, and in Friendship Games, she says putting effort into clothes and spending time on my friends are what she lives for.
Rarity also has a bit of a fascination with royalty, as she is excited to learn that Twilight Sparkle is a princess and has her own castle.*
