There’s a flacon montre of Guerlain Shalimar cologne in the dressing room of the club where Candy works as pole dancer.
It’s clear Ryan Murphy, Pose’s showrunner, is a fan of the Guerlain perfume: you may remember it was mentioned in American Horror Story: Hotel (it was Ramona Royale’s signature scent) and in American Horror Story: Roanoke (it was used by Lee Harris).
