My favorite workwear neutrals are navy and gray. The colors are reminiscent of menswear, especially men's suiting. I purchased these pants a few months ago because they were such a good deal. I packed them for a work conference and the fabric was perfect. Since they are wool I was afraid that they would be too heavy or itchy. They are actually surprisingly lightweight but still thick enough to wear in the fall. I have been so in love with this blazer too and can't stop wearing it (when I can get away with it since it's still pretty hot here!) I can't wait for cooler temperature.
