Using this costume is a breeze. First, put on the underbust corset by opening the front busk closure. Then, adjust the thick cording at the back to tighten it according to your comfort. Slip on the black halo over your head and attach the black feather wings. When it comes to maintenance, always take it to a professional dry cleaner to keep the high - quality satin fabric in good condition. Avoid getting it wet and don't try to wash it at home as it may damage the fabric and the bones. Also, be gentle when cinching the cording to prevent breaking the grommets. Store it in a cool, dry place when not in use to keep it looking its best.
