If you're on the lookout for an off-duty yet stylish look, reach for a black puffer coat and black sweatpants. To infuse a hint of stylish nonchalance into this look, add black print canvas high top sneakers to this ensemble. This one is a smart pick when it comes to an easy-to-transition look. This combination demonstrates that going from your 20s to your 30s is no reason to stop dressing casually.
