A white crew-neck t-shirt and tan shorts are a good combo worth integrating into your casual styling rotation. A pair of white athletic shoes brings a more dressed-down aesthetic to the look. As you see here, as a 20-year-old guy, you have a wide range of sartorial options.
To put together a laid-back getup with a twist, you can easily wear a navy and white horizontal striped long sleeve t-shirt and tan shorts. For times when this outfit appears too polished, dress it down by finishing off with a pair of white athletic shoes. This ensemble illustrates how to look good as you progress through your 20s.
