Technically speaking, Antebellum’s premiere was a “black carpet” event, as that was the actual color of the carpet that Janelle Monae and others walked down.
Variety reports that Monae was dressed in a quite lovely gown, though it is perhaps a little telling that her ensemble was completed with heels, a clutch, and custom made N95 face mask.
Monae says that while she felt a little overdressed, it was worth it.
Beyond that, it perhaps didn’t look all that different from a traditional red carpet in many ways.
