Carousel Boutique is the prettiest shop in all of Ponyville! (And yes, it does resemble a carousel, complete with a picture-sign of a carousel horse over the door.) It is home to Rarity and her little sister, Sweetie Belle.
The majority of Carousel Boutique's main floor is Rarity's clothling shop, workroom, and small office. In the rear of the building is a cozy-sized eat-in kitchen. The upper floor consists of three bedrooms; Rarity's is large enough to also serve as an extension of the workspace on the main floor.
Rarity's true aspirations lie in selling the most extravagant and elaborate gowns to the people of Canterlot, who buy her personalized clothing for the Grand Galloping Gala. In fact, her primary clientele seem to be from Canterlot rather than Ponyville itself, as it is seen that ponies from Ponyville don't seem to wear much clothing in the first place. Hoity Toity places regular orders for items from her "Fashions by Rarity" and "Fabulous Foals" lines for sale in his boutiques.
