Nopony’s more beautiful in Bustquestria than this big girl right here. The owner of Carousel Boutique has enough pride to display her bust to the boys. While keeping this secret hidden from Spike (and doing a good job not to get the word out), those curves can be pretty mellow for what they’re worth. While Rarity is considered by many to be Breast Pony, this claim is not entirely true. That title belongs to a more yellowish mare. Got some clothing you want to get fixed? Ask the big and generous Rarity to do that for you!
…And if you’re a male, maybe she’ll be generous enough for you to give her mallows a feel, if you have good hygiene - she doesn’t like getting dirty!
