Quinn's Amazing Technicolor Dream Coat
Does this look like the pulsating psychedelic upholstery of your acid flashbacks? Sure it does. And there's nothing wrong with that.
This coat needs nothing else. No handbag. No shoes. No jewelry. No undergarments, although some consideration should be given to the cleanliness of your undercarriage before going that route.
Quinn calls this her Amazing Technicolor Dreamcoat, although technically she stole it from Bettina's closet, as daughters are wont to do. Honestly, if her mother were cooler, she'd shop there more often.
