Can a suit-wearing man be appropriately dressed all day and into the evening without changing his clothes? Absolutely, so long as the night's event doesn't require either jeans or black tie. It's just a matter of choosing adaptable clothes in the morning.
Emulate the civilian in the illustration by starting the morning with a plain dark gray or dark navy suit, white shirt with french cuffs, white linen pocket square and black calf shoes (much as I like suede, shoes should reflect light at night). Carry a more formal necktie with you during the day and don it before the evening begins. Personally, I prefer satin in shades of maroon, light blue and gold. And voilà.
Advanced students may choose to carry a change of shirt in addition to a necktie, forgoing the white shirt in daytime for something more flattering. But it's not required.
