BritWeek is celebrating Downtown Abbey in authentic style this weekend, and it’s pulling out all the stops at the swank Fairmont Miramar. While tickets to this exclusive party are posh-priced, entry will transport you to the past with meticulous details that even the Dowager Countess would approve of. We’re talking a vintage flapper dress code, pre-prohibition cocktails, elegant old-fashioned dishes from FIG, live 1920's tunes, dance performances and even vignettes. For an extra $100, VIP tickets get you a pre-event reception and meet-and-greet with producer Gareth Neame and cast member Laura Carmichael (Lady Edith). The historical fun will also be charitable— proceeds benefit a mentoring program.
