Rock a white polo neck sweater with khaki chinos to be the embodiment of rugged sophistication. And if you need to instantly up the style ante of this look with a pair of shoes, complete this outfit with tobacco suede loafers. There's no nicer way to brighten up a gloomy autumn day than an on-trend look like this one. Searching for dressing ideas for gents in their thirties? This combination is great inspo.
