This laid-back pairing of a black crew-neck sweater and charcoal skinny jeans is very easy to put together in no time flat, helping you look stylish and ready for anything without spending too much time searching through your closet. For something more on the daring side to finish off this look, add black rain boots to this getup. As you can see here, it's very easy to look on-trend and stay snug when cooler weather comes, all thanks to looks like this.
