This casual combo of a white and black print crew-neck t-shirt and charcoal chinos is ideal when you need to look stylish in a flash. Complement this look with black leather derby shoes for an on-trend on and off-duty mix. Seeing as it's blazing hot outside, this combination appears ideal and entirely summer-appropriate. When it comes to casualwear for gentlemen in their thirties, this getup looks nice on most gents.
