I didn't even recognize her. That frizzy hair made her face look wider or something; on Palace, she's got her hair slicked back into a queenly hairstyle ('cuz she's the Queen, natch). I only found out it was her when I looked the show up on Koreanwiz. What a shock; in fact, I didn't believe it at first and had to go stare at some photos from the shows. She plays a totally different character, very refined and subdued.
PS - Palace is excellent fun, very entertaining. See it if you can.
From Dae Jang-geum: Sun-dol: "Are you trying to dry me up and kill me? Why do you say the same things over and over every day? Rather, come and hit me once! Aigu!" But then: Dr. Lazarus: "By Grabthar's hammer, by the suns of Warvan... You shall be avenged."
