Using this Barbie princess costume is super easy. First, help your little one put on the pink ballerina dress. Make sure the sequin logo on the chest is centered. Then, gently place the headband with the glittering gold tiara on her head. When your child is done wearing the costume, take it off carefully to avoid tearing the delicate tulle and organza. To clean the dress, hand - wash it in cold water with a mild detergent. Do not wring it out, just gently press out the excess water. Hang it to dry. For the tiara, you can use a soft cloth to wipe off any dust. Keep the costume in a cool, dry place when not in use to maintain its quality.
