To wear this prom dress, simply zip it up from the back using the zipper. When choosing a size, you can go with the standard size if it fits you well, or opt for custom sizing for a perfect fit. For maintenance, it's best to dry - clean the satin fabric to keep its quality and shine. When storing the dress, hang it on a wide - hanger to prevent wrinkles and maintain its mermaid shape. Avoid exposing it to sharp objects to prevent tears. If you spill something on it, clean it gently as soon as possible.
