When it comes to timeless refined style, this pairing of a light blue dress shirt and dark green wool dress pants doesn't disappoint. If you need to immediately dress down this getup with footwear, why not throw a pair of dark brown leather casual boots into the mix? This getup is basically a staple if you want to be equipped for this winter season and look equally stylish. As a gentleman in his 30s, you want to start dressing with more elegance. If that's the case, getups like this are a tested option.
