To wear this prom dress, first step into it carefully and zip it up at the back. Adjust the one - shoulder strap for a perfect fit. The built - in bra provides support, so you don't need to wear an additional one. When it comes to cleaning, it's best to take it to a professional dry cleaner to keep the fabric and applique details in good condition. Store the dress on a wide - shouldered hanger in a cool, dry place to prevent wrinkles and damage. Before the event, give it a quick steam to remove any minor creases. And don't forget to check the size chart to ensure you have the right fit. If you've chosen a custom size, double - check your measurements to avoid any issues.
