This is the simplest men’s clothing you can wear – blue blazer, white shirt, gray pants. Fit and accessories transform it. Remember that men’s style isn’t about wearing something wild, it’s about execution. If this gentleman had gotten even one thing wrong, he might have ended up looking like a security guard. Instead, he looks ready to take on the world.
(One note: his buttons are black, or perhaps navy. That would usually suggest a suit coat. If you’re in this situation, feel free to dump brass buttons, but go with something contrasting, like white mother-of-pearl or brown horn.)
