Putting together a navy suit with a navy waistcoat is a smart choice for a smart and elegant ensemble. If you want to instantly dress down this outfit with one single item, why not add a pair of navy and white canvas high top sneakers to this ensemble? This one will play especially well come blazing hot summer days. As you're getting to your 30s, you want to start dressing with more refinement. That's when inspiration like this is very useful.
