Such essentials as a suit and a white and black long sleeve shirt are an easy way to infuse some refinement into your current casual arsenal. If you need to immediately play down this getup with shoes, introduce a pair of olive suede desert boots to the mix. During the colder months, when comfort is above all, it can be easy to settle for a less-than-stylish outfit. But this outfit is a shining example that you totally can stay comfortable and remain stylish during the colder months. Wondering how your collection should look as you go into your 40s? This pairing is the perfect answer.
