Wear a suit with a navy waistcoat to look like a true fashion maven. Finishing with a pair of navy and white canvas high top sneakers is a fail-safe way to add a hint of stylish nonchalance to your ensemble. No doubt, it's easier to work through an extremely hot summertime day in a summery combination such as this one. Wear this pairing to look a bit dressier than a regular 20-something.
