To wear this dress, simply slip it on over your head. It's perfect for a casual day out in summer, like a picnic in the park or a stroll on the beach. When it comes to sizing, refer to the size chart as it fits true to size. For maintenance, always hand wash it in cold water to keep the colors vibrant and the fabric in good condition. Avoid using hot water or a washing machine as it might damage the delicate rayon fabric. After washing, hang or line dry it. Don't put it in the dryer as the high heat can shrink the dress. And that's all you need to know to enjoy this beautiful dress for a long time!
