For Abbi: You might as well wear matching outfits from Soulstice, right? Get a black Nike tank top, write the word "Trainer" across the front, and wrap a blue bandana around your ponytail.
For Trey: A black Nike tank top with the word "Trainer" like Abbi's, with a blue bandana and some eye black. Make sure you pair the top with athletic shorts and sneakers.
