For an ensemble that's super simple but can be styled in a variety of different ways, consider wearing a grey hoodie and a white short sleeve shirt. Wondering how to round off? Throw a pair of grey athletic shoes in the mix for a more laid-back take. As the weather starts getting warmer, it's time to get rid of those heavy winter gear and opt for something lighter, like this look here. This combination illustrates that passing the big 3-0 is no reason to shed casual style altogether.
