Consider teaming a charcoal crew-neck t-shirt with beige chinos if you want to look laid-back and cool without much work. A great pair of white canvas slip-on sneakers ties this look together. So if it's a baking hot warm weather afternoon and you want to look stylish without putting too much effort, this outfit will do the job in next to no time. You can take inspiration from ensembles like this if you're in your early 20s and you want to take a more mature approach to your personal style.
