1. glittering, especially with tinsel; decked with garish finery.
1. imitation gold leaf; tinsel; false glitter.

Jubilation is the dominant mood when- and wherever a Christo/Jeanne-Claude project is realized. I have witnessed it time and again—32 years ago, in Loose Park, Kansas City, overlooking its Wrapped Walk Ways, every inch of the winding itinerary paved with bright clinquant stuff, of which Christo remarked: “When the sunlight falls on that nylon and sets it sparkling, it’s very beautiful.” – Leo Steinberg, “Christo’s ‘Over the River’: An Act of Homage,” New York Review of Books, December 3, 2010
Clinquant entered English in the late 1500s and ultimately derives from the Dutch klinken meaning “to sound.”
