Orange leather high top sneakers add a little edge to this ensemble. Those who wonder how to rock cool casual style as you make your way through your 20s, you have your answer.
For a look that's super straightforward but can be styled in a myriad of different ways, dress in a black puffer jacket and a long sleeve t-shirt.
