For something on the cool and casual side, wear this pairing of a light blue chambray long sleeve shirt and grey chinos. Serve a little mix-and-match magic by slipping into olive athletic shoes. When leaves turn yellow and red and autumn sets in, you'll appreciate how great this look is for transeasonal weather. You can take cues from outfits like this if you've passed the big three-oh and you want to take a more mature approach to your style.
