How to wear: Put on this dress like you would any other dress, using the back zipper to get in and out. The button on the open back adds a nice touch and can be easily fastened. When to wear: This dress is great for holiday parties, especially New Year's Eve. It will make you stand out in the crowd. Maintenance: Hand wash it in cold water to keep the sequins in good condition. Don't use a washing machine as it might damage the sequins. After washing, hang or line dry it. Avoid wringing it out to prevent the fabric from getting stretched. Size: It fits true to size, so you can choose your regular size. If you're between sizes, you can consider going up for a more comfortable fit.
