I say something elegant, but comfortable. If you like skirts or dresses, a pencil skirt or so is a nice look. Personally, I would stick to navy, black, grey, oxblood red, darker plum, etc. but you can wear what you think is best. In a professional environment, navy tends to be a good, strong, confident color.
Or if you don't want to wear skirts or dresses, a nice tailored pant, button up shirt and blazer can look good. You can take the blazer off, maybe wear a sweater or cardigan, or just the blouse.
