How to use: Just put on the pajama set for a comfortable and stylish sleep or relaxation time. Note that the pajamas are hand - wash only, so avoid using a washing machine. For maintenance, gently wash it with mild detergent and dry it in a cool, shaded place. This will keep the silky satin fabric in good condition. Also, make sure to choose the right size from S, M, L, or XL for the best fit.
