Consider pairing a light blue long sleeve shirt with grey sweatpants for a no-nonsense ensemble that's also well-executed. A pair of white canvas low top sneakers looks great rounding off your getup. During the winter months, when functionality is a must, it can be easy to settle for a less-than-stylish outfit in the name of functionality. This outfit, however, is a good illustration that you can actually stay snug and remain stylish in the winter months. This pairing proves that in your thirties your styling options are in no way limited.
