The beautiful actress (who typically rocks pretty blond hair) can pretty much pull off any look she wants, and this ravishing new shade is quite striking on the star.
She told E! News during New York Fashion Week last month that she dyed her hair for her new role in Still Alice, and we think she looks simply lovely.
The brilliant color complements her fair coloring and proves to add a touch of radiance to her look quite effortlessly.
And while Bosworth's fresh beauty update was indeed for work, we totally support experimenting with brilliant colors this season.
Spring makes for the perfect time to try out an extraordinary new look, and we're loving this one on Kate so far!
What do you think of her new 'do?
