To use this bodysuit, simply step into it and zip up the side zipper. It's designed to shape your under - bust area, so make sure it fits snugly but comfortably. When it comes to maintenance, always hand - wash it in cold water. This helps to keep the shape and quality of the fabric. Avoid using a tumble dryer as the high heat can damage the spandex in the material and cause the bodysuit to lose its stretch. Also, don't use harsh detergents that might fade the color or damage the lace details. Hang it up to dry naturally. If it gets wrinkled, you can gently iron it on a low - heat setting.
