For an effortlessly sleek look, try pairing a grey chambray dress shirt with beige chinos — these two pieces play nicely together. Rev up this look by slipping into dark brown leather tassel loafers. Totally appropriate for blazing hot warm weather days, you can rock a version of this ensemble all season long. As you step into your 30s, you probably want to start dressing more professionally. If that's the case, outfits like this are a life saver.
