Pinkie Pie's Rapper outfit appears in Testing, Testing, 1,2,3, where she starts rapping about the History of the Wondercolts.

How to Go Viral
While Rarity tells the CMC about how she became so into fashion, there is a costume in her closet similar to this outfit strangely. And later in 'Pinkie Pie's room when the shirt covers Gummy's entire body while he is moving.
