For an effortlessly neat ensemble, wear a shirt and shorts — these two items play pretty good together. As you're going from your 20s to your 30s, you probably want to start dressing like an adult. If that's the case, combinations like this are perfect as inspiration.
Make a shirt and shorts your outfit choice for a fuss-free look that's also well put together. And if you need to effortlessly up your look with shoes, complete this look with a pair of navy leather slip-on sneakers. Style like this is what at the end of the day will gain you more trust and respect from your peers and everyone else.
