Yes, it’s a promotional featurette produced by The Weinstein Company, but this video of the great costume designer Sandy Powell talking about designing Carol is illuminating. Powell discusses conceiving clothing for both Cate Blanchett and Rooney Mara while keeping in mind what their sartorial choices illuminate about their characters. Also, her comment about costuming for the period — that the “look” of a decade doesn’t really kick in until halfway through as people are stuck in the fashions of the previous decade — is spot on.
