For a casually classic look, go for a white and black blazer and a crew-neck sweater — these two pieces play beautifully together. And if you wish to easily step up your outfit with shoes, why not complement this ensemble with a pair of brown suede tassel loafers? With the departure of snow comes warmer, sunnier weather and the need for a light and breezy ensemble just like this one. As you're maturing from your 20s to your 30s, you want to start dressing like an adult. In this case, ensembles like this are a foolproof option.
