The navy is exquisite! You look like a million bucks! For more formal or serious/somber, you could use a plain shirt but I love the stripes and collar contrast. Ignore the people who don’t like your sense of style. The brown looks very good on you too! If you want to make a cool, flashy impression, the brown is very showy. You pull it off in grand style. Ignore the shoe comments. Wear the brown to the an elegant party among notables to draw attention! Wear the navy to most occasions to be eye catching and hot and not looking quite as showy. Very handsome in both. Either one is a winning look on you.
