How to wear: Slip on the dress over your head and tie the halter neck at the back for a secure fit. Adjust the tie - back to your preferred tightness. Note: Make sure to measure your body accurately for custom sizing. If you're ordering a standard size, refer to our size chart. Maintenance: Hand - wash the dress in cold water with a mild detergent. Avoid wringing or twisting it. Lay it flat to dry to maintain its shape.
