In season two, episode fifteen of "New Girl," Jess and Nick have to kiss as part of the drinking game True American. During the interaction, Nick is wearing a trench coat, and Jess has on a purple bra and a red tutu.
They ultimately don't kiss wearing the outfits, but the looks are iconic in the "New Girl" fandom, making them ideal for Nick and Jess costumes, as Olivia Cunningham showed with her rendition of the ensembles.
