If you haven't seen Downton Abbey yet, you are in for a real treat! I'd call it an Edwardian soap opera (first season set in the years 1912 – 1914), and it is riveting. It has it all: mysterious pasts, jealous sisters, gay footmen, medical dramas, secret ambitions, inheritance scheming, backstabbing housemaids, smart dialogue, the legendary Maggie Smith, and .... and... AWESOME COSTUMES!!
I know many of these costumes were reused from other productions, but it doesn't matter at all. You can run these episodes on mute and just be dazed by one glorious costume change after another. Especially if you know your costume history, it is just delicious. Get a sketchbook, a big piece of chocolate cake and watch these back to back for design inspiration overload!
