Crime writer Harriet was not fully convinced that Rachel was a Traitor - until she saw her wear a red dress the day after a pivotal moment in the show.
"She'd gone in looking so sleek and professional… whereas before, she was dressed up more in child-friendly sort of yellows and dungarees and like a Minion," Harriet told BBC Local.
For contestants on the reality TV show The Traitors, it is not just what they say or how they act that shapes their fellow players' opinions of them - it is how they dress.
"What we wear says a huge amount about us," says Carolyn Mair, a chartered psychologist and author of The Psychology of Fashion. Some of the contestants used their outfits "very carefully and very well", she says.
"Their clothing becomes their character."
