A brown plaid long sleeve shirt and blue jeans are an easy way to introduce played down dapperness into your day-to-day routine. If in doubt as to the footwear, stick to white leather low top sneakers. So if it's a baking hot summer afternoon and you want to look stylish without putting in too much work, this look will do the job in next to no time. Relaxed casual ensembles for gents in their 30s aren't actually that hard, as you can see here.
