For something on the casually cool side, you can dress in a multi colored shirt jacket and light blue jeans. Rounding off with high top sneakers is a fail-safe way to inject a more casual touch into your look. This combination shows that as a gentleman in his 30s, you have a wide range of style options.
Wear a multi colored shirt jacket and navy jeans if you seek to look casually cool without putting in too much effort. Take an otherwise dressy outfit in a whole other direction by finishing with a pair of high top sneakers. Ideal if you're on the lookout for some seriously inspiring over-30 laid-back style.
