For an ensemble that's super simple but can be styled in a myriad of different ways, pair a tan shearling jacket with grey cargo pants. You could perhaps get a little creative when it comes to shoes and play down this look by wearing work boots. In winter, when warmth is essential, it can be easy to settle for a less-than-stylish ensemble in the name of functionality. But this ensemble is a bright example that you can actually stay toasty and remain equally stylish during winter. As you can see here, in your 30s your sartorial options are pretty much limitless.
