Parade your styling game by putting together a navy crew-neck t-shirt and a grey suit. Let your sartorial sensibilities really shine by complementing your getup with a pair of white athletic shoes. You'll always look stylish even despite the scorching heat if you have this look in your front hall closet. You can take inspiration from outfits like this if you're in your mid-20s and you want to take a more adult approach to your personal style.
