To wear these Panetto plaid trousers, simply pair them with a white blouse for a weekday outfit or add the coordinating blazer for a more dressed - up look. When it comes to washing, follow the care label instructions. Usually, it's best to wash them in cold water on a gentle cycle. Avoid using harsh detergents as they can fade the plaid pattern. Hang them to dry to maintain their shape. Iron on a low - heat setting if needed. Store them folded or on a hanger in a cool, dry place to keep them in good condition.
