Pop culture right now is all about Play. Apparently, Rainbow Bright was a Material Girl, and the little girls who grew up playing with her haven't forgotten that.
The look of artists like Nicki Minaj, Katy Perry, and Lovefoxxx (below) is Rainbow Bright, but with a decidedly...erotic twist.
This stuff is an aesthetic sugar rush, a hipster fantasy cracked out on agave syrup. It's excessively sweet, and excessively excessive. Decked out with jobs, adulthood, and real responsibilities, maybe the Rainbow Bright generation just really misses playtime.
