If the setting allows a relaxed menswear style, you can rock a white short sleeve shirt and khaki chinos. Add a pair of navy and white athletic shoes to this ensemble to infuse an element of stylish effortlessness into this look. So so as you can see, it's an on-trend, not to mention spring-appropriate, outfit to have in your transeasonal arsenal. Wondering how to master casual looks as you work your way through your 20s? This combination is an amazing example.
