To use this flower girl dress, simply have the little one put it on through the zipper at the back. It's very easy to wear. When it comes to care, hand - wash it gently in cold water to keep the lace and tulle in good condition. Avoid using harsh detergents as they may damage the fabric. Hang it to dry to prevent any shrinking or misshaping. Before ordering, be sure to measure the child accurately according to our size chart. If you choose custom sizing, double - check the measurements you provide in the email. Also, note that the processing and shipping times are estimates, so plan ahead for special events.
