To use this set, you can wear the babydoll as a single piece or convert it into a two - piece. Just adjust the straps on the cage - design back top for a perfect fit. The matching thong is there to complete the look. When it comes to maintenance, always hand wash it in cold water. Do not use bleach as it may damage the fabric. Also, avoid ironing as the heat can ruin the lace trim. Keep it in a cool, dry place to maintain its quality.
