Well, I like to wear linen suits in summer, that is if I do wear a suit. I prefer to wear tan or cream. Otherwise I'm usually wearing odd jackets of various types. Why because they allow me to wear many different colors and combinations of summer textures. For instance; linen, seersucker, tropical wool, cotton, and wool blends. I like to mix them with silk ties.
If I should have something important to do this is probably what I wear most a tan cotton suit with patch pockets and three buttons so I could wear a bow tie without much shirt showing.
