To wear this dress, first put on the bodice and fasten the corset. You can choose to attach the detachable sleeves for a different look. When it comes to sizing, if the standard sizes don't fit you, don't worry! Just measure your bust, waist, hips, and height, and either email us or add the measurements at checkout. As for maintenance, spot - clean the tulle fabric gently with a mild detergent. Avoid machine - washing to prevent damage. When not in use, hang the dress in a cool, dry place to keep its shape.
