To wear this dress, simply step into it and zip up the back. Make sure the off-the-shoulder part sits comfortably on your shoulders. Since it has built - in bra support, you don't need to wear an additional bra. When it comes to sizing, if the standard sizes don't fit you, just provide your measurements as described. After the event, dry clean the dress to keep its chiffon fabric in good condition. Avoid wearing sharp jewelry that could snag the fabric. And if you get any stains, take it to a professional cleaner as soon as possible.
