For something more on the relaxed end, consider pairing a brown harrington jacket with a crew-neck t-shirt. A nice pair of mustard suede loafers is an easy way to breathe an added dose of polish into your look. Come super hot sunny days you want to feel cool and on-trend –– this look is just the right one. Off-duty ensembles for guys over 30 aren't actually that hard, as you see.
