For a casual look, invest in some classic staples such as a leather jacket, selvedge denim jeans, and a good beanie. Then mix in trending items like flannel shirts, colorful cardigans, and oversized jumpers. If you want to dress up more, a classic coat such as a pea, blazer, or trench coat is a great option, paired with a woolen suit or chinos with warm socks and dressy boots.
