For an outfit that's super straightforward but can be styled in a multitude of different ways, try teaming a sweatshirt with a tan crew-neck t-shirt. Infuse an element of stylish nonchalance into this outfit by wearing a pair of beige rubber sandals. Needless to say, you're looking at a wonderful pick for a summer day. This combination proves that as a younger gent, you have a wide range of styling options.
