White and charcoal is a tonal pairing with just enough gap to look deliberate, the grey grounding the white so it doesn't read like a tennis kit. The tee's a wrinkle-resistant travel knit that comes out of a bag ready. Picture a warm arrivals hall, bag over a shoulder, sun through the glass. A neutral top over white shorts packs flat and pairs with anything else you brought.
Finish with white leather sneakers, a black belt, and a low cap.
