Go for something stylish yet on-trend in a charcoal blazer and black dress pants. A pair of oxford shoes is a smart idea to complement your ensemble. With the departure of winter come warmer days and more sunlight and the need for a cool look just like this one. As you're transitioning from your 20s to your 30s, you probably want to start dressing more elegantly. If that's the case, ensembles like this prove useful as a source of inspiration.
