This casual combination of a grey crew-neck t-shirt and black ripped skinny jeans comes to rescue when you need to look dapper but have no time to spare. Complement this getup with black leather casual boots for an extra touch of style. We know it's hard to stay fashionable in extreme weather, but this outfit is proof that it's quite doable. This combination illustrates how to keep killing in the casual fashion department as a 30-something.
