I have a question on this topic actually... I just recently got a great deal on a mid-tan 3-button suit, I was curious what kind of shirt colors/textures go well with it? I was just going to wear a white french oxford underneath it, but would like to try for something a little more inventive. Not really in the know about suits brown ranges, as this is my first one.
I love sky blue and French blue shirts with tan suits. Sets off a nice contrast.
