Deep blue and true khaki sit on opposite ends of the temperature scale, which is exactly why the pairing works without any real effort. The tee's soft, breathable knit is built for a long layover, whether that means layered under a jacket or worn alone once you land somewhere warmer. The slim tech pant's stretch and wrinkle resistance mean it looks the same walking off the plane as it did walking on.
Finish with white leather sneakers and a canvas weekender bag.
