If you're looking for a casual yet on-trend look, go for a navy bomber jacket and navy sweatpants. Feeling venturesome today? Play down this getup by finishing off with white leather high top sneakers. A great, less conservative getup for gents over 30.
For a casually cool ensemble, wear a navy bomber jacket and navy vertical striped chinos — these two items work really cool together. White leather high top sneakers will add a more casual finish to an otherwise standard look. Overall, a good example of casual style for 30-year-old guys.
