To wear these Rori cargo trousers, simply pull them on like regular pants. The drawcord at the waist and ankles allows you to adjust the fit as you like. They're great for casual outings during the day. When it comes to maintenance, machine wash them in cold water on a gentle cycle to keep the fabric in good shape. Avoid using bleach as it might damage the color. Also, as mentioned, the color can look different in various lighting, so don't be surprised if it seems a bit different in sunlight or under indoor lights. And remember, these trousers come in size XS as shown on the models, so choose the right size for you.
