Who: Sophie Turner.
When: Sunday, April 11.
Where: The Season Six premiere of Game of Thrones in Hollywood, California.
What: A one-shouldered bright eggplant Stella McCartney gown.
Why: Everyone knows purple is the color of royalty — and, while her McCartney gown might tend a bit more towards the fuchsia end of the spectrum, Turner completes the look with a braided crown wreathing her head.
