When you're ready to wear this beautiful prom dress, step into it carefully from the bottom. Adjust the bodice to sit comfortably around your torso, and make sure the off - the - shoulder sleeves are in place. As you walk, let the mermaid silhouette and thigh - high slit add a touch of elegance and flair. When it comes to care, avoid machine washing as the sequins might get damaged. Instead, take it to a professional dry - cleaner. Store the dress on a wide - shouldered hanger to maintain its shape. If you notice any loose sequins, you can use a little fabric glue to reattach them. And always keep it away from sharp objects to prevent tears.
