For an off-duty look, consider teaming a grey crew-neck sweater with charcoal skinny jeans — these pieces fit perfectly well together. To bring some extra flair to this getup, complete this outfit with a pair of black leather casual boots. So as you can see, this getup is a really savvy option, especially for weird transition weather, when the mercury is falling. Wondering how your arsenal should look as you move through your 20s? This pairing is the perfect answer.
