Lily Rabe as Sister Mary Eunice wears a red lipstick.

There’s an interesting behind-the-scene story about this lipstick. Its shade – Ravish Me Red – is a real colour by Revlon, but the show’s make-up artist Eryn Krueger Mekash explained they actually used a Julie Hewett lipstick on Lily, aptly called Femme Noir, a gorgeous blue-based scarlet red.
