For a casually stylish ensemble, consider pairing a white long sleeve shirt with white jeans — these items fit really well together. If you wish to immediately dress down your getup with one item, why not complement this getup with a pair of grey athletic shoes? As roasting hot sunny weather settles in, it's time for light and breezy combos like this one. As you can see, after 30 you have a wide array of styling options.
