To wear this beautiful prom dress, first put it on over your head and adjust the cold - shoulder sleeves so they sit comfortably on your shoulders. Zip up the back carefully. Since it has a built - in bra, you don't need to wear an additional one. For sizing, always check the size chart first. If you're getting a custom - sized dress, make sure to take accurate measurements at home. When it comes to maintenance, it's best to dry - clean this dress to keep the lace and fabrics in good condition. Avoid hanging it on a sharp hanger as it might damage the delicate lace. Store it in a cool, dry place, preferably in a garment bag to protect it from dust and dirt.
