A long sleeve shirt and a white long sleeve t-shirt? It's an easy-to-achieve outfit that you can work on a day-to-day basis. A pair of white canvas high top sneakers effortlessly amps up the fashion factor of your look. So as you can see, this combination is a really nice choice, especially for awkward transition weather, when the temperatures are dropping. This combo demonstrates that going through your late 20s is no reason to stop dressing casually.
