This lingerie set is easy to wear. Just put on the triangle bra and matching panties. When wearing, make sure the bra fits well around your bust and the panties sit comfortably. For washing, it's best to use a gentle cycle in cold water. Avoid using harsh detergents as they can damage the lace. After washing, lay it flat to dry instead of hanging to prevent stretching.
