The question on everyone’s mind last night was: Why the heck are those leotards so shiny? Slate had the same question and was kind enough to provide the answer. The fabric is called Mystique and is a spandex base that is then covered with small foil dots. The result? A molten, plasticky, shiny, glorious mind-fuck. A gymnastics coach told Slate that the fabric reflects “current fashion,” and it’s also much cooler than crushed velvet.
