A white print crew-neck t-shirt and grey chinos are absolute menswear must-haves if you're figuring out an off-duty closet that holds to the highest style standards. Grab a pair of grey leather slip-on sneakers to make the outfit slightly classier. Super cool and entirely summer-appropriate, you can wear a variation of this outfit throughout the summertime. This ensemble is probably exactly what you've been looking for as a young gent.
