This casual combination of a grey cardigan and blue denim shorts is super easy to pull together without a second thought, helping you look seriously stylish and ready for anything without spending a ton of time rummaging through your wardrobe. For something more on the cool and laid-back side to complete your getup, add a pair of white leather low top sneakers to the equation. We're loving that this look is great come super hot summer days. Perfect if you're looking for some seriously inspiring off-duty style for guys in their 30s.
