This combination of a white and red and navy plaid long sleeve shirt and black jeans is undeniable proof that a safe casual ensemble can still be really interesting. The whole ensemble comes together quite nicely if you complement this outfit with white canvas low top sneakers. This getup is also great if you're on the lookout for hot weather wear to make a tedious day more bearable. Ideal if you're looking for some amazingly inspiring off-duty style for mature gents.
