To use this dress, simply help the little girl put it on. The convertible belt can be adjusted to make it fit perfectly. When wearing, make sure there are no sharp objects nearby that could damage the delicate tulle and lace. For maintenance, it's best to hand - wash the dress in cold water with a mild detergent. Avoid wringing it out to prevent distortion. Hang it to dry. If there are any stains, treat them gently as soon as possible. When not in use, store the dress in a cool, dry place, preferably in a garment bag to protect it from dust and moths. Also, always double - check the size according to our size chart to ensure a proper fit.
