However, one of the most memorable moments of the entire film is undeniably the scene in which Priestly analyses in great detail the colour of a single jumper. “What you don’t know is that that sweater is not just blue,” she says. “It’s not turquoise. It’s not lapis. It’s actually cerulean.” Priestly then goes on to explain the history of the specific shade, outlining its various significant runway appearances, and of course, solidifying cerulean as a colour never to be forgotten among the fashion set.
