Opt for a grey print sweatshirt and blue ripped skinny jeans if you're looking for a look option for when you want to look casually stylish. Add a pair of white and black leather low top sneakers to the equation to immediately kick up the fashion factor of any look. This one is a smart choice when it comes to planning a well-coordinated ensemble for summer-to-fall weather. This outfit demonstrates that reaching your 30s is no reason to shed casual style altogether.
