This crop top was worn during the performance of Nasty and Rhythm Nation (Originally by Janet Jackson) performed by Jacob Artist (Jake Puckerman) and Melissa Benoist (Marley Rose). This performance was done in season 5 episode 7 titled “Puppet Master.” Unlike the original Cheerios uniform this top was made by Arden B.
Since Arden B is not a typical cheer uniform company. It is hard to say if this was made specifically for this episode or if the WMHS colors were added after purchase. More research would have to be done to confirm the creation of this wardrobe item.
The name Chelsea is written on the tag. Though the name can not be found on IMDB. It is assumed that Chelsea was a background dancer during this performance (and possibly others as well). It is unknown if Chelsea is the performer’s name or an unknown character’s name.
