For a look that's pared-down but can be styled in a multitude of different ways, pair a white vertical striped blazer with navy jeans. Complement this ensemble with a pair of navy slip-on sneakers and the whole outfit will come together perfectly. Keep this ensemble ready to go come warmer days, and rest assured, you'll save a ton of time crafting what to wear on more than one morning. A no-brainer combo appropriate for young gentlemen who like casual clothing.
