To wear this dress, simply slip it on over your head and tie the back to get a perfect fit. This dress is suitable for many occasions like parties, dates or casual outings. When it comes to maintenance, it's best to dry clean it to keep the tulle fabric in good shape. Avoid washing it in a washing machine as it may damage the ruffles. As for sizing, if you're between sizes, it's recommended to order the larger size. And don't forget, if the standard sizes don't fit you, you can always get a custom - sized dress by providing the necessary measurements.
