To wear this dress, simply step into it and zip up the back. The built - in bra provides support, so you don't need to wear an extra one. When choosing a size, refer to the size chart. If you need a custom size, you can provide your bust, waist, hips, hollow - to - hem (for short dress) or hollow - to - floor (for long dress), and height measurements before or after ordering, or add them to the note box at checkout. For maintenance, it's best to dry clean this taffeta dress to keep its shape and color. Avoid wearing sharp objects that could snag the ruffles. Store it in a cool, dry place, hanging it up to prevent wrinkles.
