This pairing of a grey waistcoat and a light blue dress shirt is the picture of class. Does this look feel all-too-polished? Introduce dark brown suede tassel loafers to mix things up. So if you're on the lookout for a look that's on-trend but also feels totally spring-appropriate, this one fits the bill. The ability to pull off ensembles like this is one of the perks of moving into your 30s.
