Rarity is a white fashonista unicorn. She makes clothes for a living, and also does it for favours for her friends. She lives at carousel boutique by herself, though her younger sister Sweetie belle often comes to stay or visit. While she may only be living in a small boutique in Ponyville, that doesn't mean she doesn't have important clients: She's made dresses for many important occasions and ponies, like the Canterlot wedding, Sapphire shores and many more. Spike (the baby dragon) is a not-so secret admirer of Rarity, and is always eager to help her out in any way he can. She also has a white persian cat named Opalscence.

Her cutie mark is three blue diamonds.

She represents the element of Generosity
