These Seventy's navy stretch trousers are super easy to style. You can wear them for casual outings or semi - formal events. Just pair them with a simple lightweight top. For maintenance, it's best to follow the care instructions on the label. Usually, machine - washing in cold water and tumble - drying on low is a good way to keep them in shape. Avoid using harsh detergents as they might damage the stretch fabric. Also, don't iron them on high heat, as it could ruin the flare leg silhouette.
