For an outfit that's very simple but can be flaunted in a great deal of different ways, wear a brown corduroy long sleeve shirt with light blue jeans. This ensemble is finished off nicely with a pair of white leather low top sneakers. Seeing as it's baking hot outside, this look seems perfect and entirely season-appropriate. Those who are curious how to pull off modern casual dressing as you progress through your 20s, you have your answer.
