Such must-haves as a brown polo and khaki dress pants are an easy way to introduce a sense of masculine elegance into your casual wardrobe. To add an extra dimension to your look, add brown suede loafers to the mix. When leaves turn yellow and red and fall settles in, you'll love this combo as your go-to for awkward transition weather. As you mature into your 30s, you probably want to start dressing in a dressier manner. In this case, ensembles like this become a great source of inspiration.
