This combo of a blue hoodie and a crew-neck t-shirt is undeniable proof that a safe casual look can still be really interesting. Let your outfit coordination chops really shine by finishing this getup with a pair of beige suede low top sneakers. You might be thinking that just because you need to get bundled up you have to sacrifice good style, but it's just not true, and this outfit is hard proof. Overall, an ideal example of off-duty style for 30-something gentlemen.
