For an ensemble that's city-style-worthy and casually classic, reach for a brown turtleneck and grey check dress pants. A great pair of tassel loafers is an easy way to infuse an added touch of sophistication into this look. So as you can see, it's extremely easy to look awesome and stay comfy when fall arrives, all thanks to combinations like this. Overall, a smart option if we're talking style for gents in their 20s.
