Figured I needed some patterned pants so I ended up getting two different pairs. I got some white and blue Paul Smith London cotton pants; I don't know the exact term for the pattern but it's alternating rows of really small diamond/squares so the pants look sort of like a solid pale blue from a distance. The other pants is a pair of cotton Nicole Miller trousers that are yellow/beige with a medium-sized navy blue windowpane pattern. It's a little tacky, but I got it cheap off Ebay so I don't really mind. I need some recommendations of shirt styles and colors (are patterned shirts totally out of the question?) to wear with these pants. I'm thinking plain white would go well with both of them but I'd prefer to try some more colors with the pants but not end up looking silly. As for when to wear them, I assume daytime (not business) casual during the spring/summer season would be best, or could I pull off wearing them out to clubs or parties?
