Counter culture era dress
Like Britney Spears and Justin Timberlake's iconic denim outfits. High in sexual dimorphism but here's a comparison:

You can tell which one is from Counterculture-era by the amount of rhinestones and colors/shades their outfits have. The outfits of Britney and JT have less rhinestones and were closer to being monotone than the outfits of Katy Perry and Riff Raff. Not to mention their accessories and Raff's tattoos. The outfits of Perry and Raff weren't even denim outfits, therefore have slightly less quality (if not completely less quality) than the outfits of Britney and JT.
