To wear these Rene green pants, simply pair them with a lightweight top. They're great for both casual outings and semi - formal events. When it comes to maintenance, it's best to follow the care instructions on the label. Usually, a gentle machine wash in cold water is a good idea. Avoid using harsh detergents as they can damage the stretch blend fabric. Also, don't dry them on high heat; a low - heat setting or air - drying is recommended. Keep them away from sharp objects to prevent snags on the knit material.
