To style these Estasi black straight-leg trousers, you can easily pair them with a cozy knit sweater for a casual weekend look, or a crisp blouse for a more formal occasion. When it comes to accessorizing, a simple belt can add a touch of style. As for care, it's best to follow the washing instructions on the label. Usually, a gentle machine wash in cold water and air drying will keep them in great shape. Avoid using harsh detergents that might damage the fabric. Also, be careful when ironing; use a low - heat setting to prevent any shiny marks on the black fabric.
