This casual combination of a white and navy horizontal striped crew-neck sweater and black leggings is extremely easy to pull together without a second thought, helping you look stylish and ready for anything without spending too much time going through your wardrobe. A pair of brown leather knee high boots will bring a different twist to an otherwise utilitarian ensemble. So as you can see, this getup is a really great pick, especially for awkward fall weather, when the temperatures are dropping.
