Two days ago Holliday attended alongside the cast and crew (Lia Williams, Ben Chanan, Rosie Alison, Derek Ritchie, Daisy Waterstone, Killian Scott, Ben Miles) of The Capture, to Season 3 photocall. And on that day, the crew released the information that The Capture will premiere BBC on March 8th.
I believe she is wearing a setin top with lace trim by Maje and a velvet suit by Sezane from the fall/winter 2020 collection, which we added to our Holly’s closet.
