When you wear this royal blue prom dress, you'll be the center of attention at the prom. To put it on, simply step into it and zip it up from the back. Make sure to check the size carefully before ordering. If you choose custom sizing, provide accurate measurements. After the event, you can gently hand - wash the dress in cold water with mild detergent. Don't wring it out. Instead, lay it flat to dry. This will help keep the satin fabric looking its best for a long time.
