I was a fan of Cheyenne Jackson's costume in Xanadu. Though I'm pretty much a fan of anything Cheyenne Jackson is wearing.
I'll also chime in my support for Nina Arianda's boots in Venus in Fur. I was also a fan of her black robe ensemble in Born Yesterday. (Though, again, I'm pretty much a fan of anything Nina Arianda is wearing.)
I also thought some of the dresses Patti LuPone wore in Anything Goes were rather sexy. The dress she wore during "You're The Top," in particular, was incredible sexy IMO.
When I see the phrase "the ____ estate", I imagine a vast mansion in the country full of monocled men and high-collared women receiving letters about productions across the country and doing spit-takes at whatever they contain.
