The styling capabilities of a mustard sweatshirt and navy sweatpants ensure you'll have them on regular rotation. Grey athletic shoes are guaranteed to give a touch of stylish nonchalance to this look. So as you can see, this combo is a really good pick, especially for unpredictable fall weather, when the temperatures are dropping. Think over-50 gents can't pull off cool off-duty outfits? This combo is hard proof of otherwise.
