Rainbow Dash and Rarity have a chalk-and-cheese relationship at the best of times, but when Dash makes a mess of a special effect for a fashion show in front of some of Canterlot's most influential ponies, Rarity is furious. Embarrassed and miserable, Rainbow believes she deserves to be alone for a while. Her friends may have other ideas.

Lightly inspired by the Rainbow Rocks song "Shine Like Rainbows", hence the story's title, but this is not an Equestria Girls fic.
