To maintain the sleek and structured look of your black belted midi skirt, machine wash on a cold, gentle cycle or hand wash using a mild detergent. Remove the belt before washing to preserve its quality. Air dry on a hanger to avoid wrinkles, and iron on a low to medium setting from the reverse side if needed. Style it with a crisp button-down shirt for a polished work look or pair with a fitted knit for a more relaxed vibe. Complete the outfit with pointed heels or ankle boots and a structured handbag for an effortlessly sophisticated finish.
