Who said you can't make a style statement with an off-duty outfit? Draw the attention in a beige raincoat and navy chinos. To give this outfit a more relaxed aesthetic, introduce a pair of navy and white athletic shoes to your outfit. So as you can see, it's extremely easy to look sharp and stay comfortable come chillier days, all thanks to combinations like this. When it comes to casual fashion for middle-aged gents, this combination is perfect.
