To wear this dress, simply zip it up from the back. The off-the-shoulder style might need a little adjustment to sit perfectly on your shoulders. When it comes to sizing, if you're between sizes or want a perfect fit, go for our free custom sizing option. Just measure your bust, waist, hips, height, and the appropriate hollow to hem or floor length as described in the product details. For maintenance, it's best to dry clean this chiffon dress to keep its quality and shape. Avoid washing it in a machine as it may damage the fabric. Store it in a cool, dry place on a hanger to prevent wrinkles.
