Rainbow Dash is having an awful, terrible, no-good very bad day. Nothing seems to be going right! Pinkie Pie, being a dutiful friend, steps in to whisk her friend away to a one-day-only shop called the Make Me Better Boutique. But will she be able to cheer up her best friend? And will that cheering up lead to something ... more?

(Femshipping, but no wilder than a G/PG movie. Fun fact: This was one of the first (possibly the first?) fics that explored the idea of 'wing boners.')
