I realized that I was lacking in pegasi, so I made twins.
Dawns Light "Dawn" (pink mane) is the girly twin. She hates to get her hooves dirty and is obsessed with being pretty. Because of her obsession with beauty, she often tries to get her sister to wear girly things and put on make up. Although, she does have a slightly snappy attitude and often talks like a typical teenage girl. Her cutie mark is a perfume bottle for making perfume, but she has yet to get her own perfume in stores. She works at Angelique Boutique, a store owned by a pony named Angelique. She doesn't have a fancy important job there, much to her dismay. She is only a salespony.
Daybreak "Day" (blue mane) is the tomboyish twin with a musical side. She's a bit of a daredevil and isn't afraid to get her hooves dirty. She loves to go on adventures and discover new beats and tunes. She may be a tomboy at heart, but that doesn't stop her from looking fashionable. She may not seem like it, but she enjoys getting new clothes and accessories almost as much as her sister. Much like her sister, she also talks a bit like a teenage girl. Just a more... boyish one. Her cutie mark is a music note with a blue lightning bolt on the end. She spends the majority of her time writing upbeat songs and making new dances.
These two sisters are super close and they do everything together. They're not just sisters, they're best friends.
::EDIT:: You know how many comments I get comparing them to Rarity and Rainbow Dash even though they have key differences? A lot. I don't need more telling me the same thing. It's annoying. But more than half of you wont read this anyways so I guess my efforts are futile.
