Combining a crew-neck sweater and brown wool dress pants will be irrefutable proof of your sartorial expertise. A great pair of brown oxford shoes is an easy way to give an extra dose of class to your outfit. So as you can see, it's a kick-ass, not to mention season-appropriate, outfit to have in your transeasonal rotation. As a 30-something, you probably want to start dressing in a dressier manner. If that's the case, getups like this are a never-failing option.
