Celebrate the Red, White & Blue
Slate blue 3-piece suit (almost any shade of blue or grey works here) is the foundation. Keep the suit simpler if the accessories will be bolder.
Special designed multi-color brogues & coordinated shadow stripe socks for dandification.
Patriotism on full dispaly here, targeting only the main color scheme.
Vest linings make a suit unique and personalized. I often attempt to even coordinate the lining with the outfit, but that aspect is certainly not critical.
The undone bowtie and unbuttoned vest look, with a nice cocktail, always has a unique visual poignancy.
Coordinating the subtleties, the cuff links and the watch. It becomes eye candy.
