To style a casual shirt for a smart-casual look, women have several options. Start by selecting a well-fitting casual shirt in a versatile color or pattern. Pair it with tailored pants or dark jeans for a polished appearance. For a more feminine touch, tuck the casual shirt into a skirt and add a belt to define the waistline. Layering the casual shirt under a blazer or structured jacket can instantly elevate the outfit. Complete the look with accessories like statement jewelry, a stylish handbag, and shoes that strike the right balance between casual and dressy. By mixing and matching different elements, a casual shirt for women can be transformed into a fashionable ensemble suitable for smart-casual occasions.
