Combining a pink dress shirt with grey dress pants is a great idea for a sharp and polished outfit. Rock a pair of brown suede double monks to give a dash of stylish nonchalance to your outfit. This combination is also great if you're looking for summertime wear to get through a tedious day. As a guy in his 30s, you want to start dressing in a sleeker manner. In this case, combos like this are a real life saver.
