To use this cute flower girl dress, simply put it on your little one. When ordering, always check the size chart carefully as our child size isn't based on age or height. If you need a custom size, email us the required measurements before or after your order. For maintenance, hand - wash the tulle fabric gently in cold water. Avoid using harsh detergents as they may damage the fabric or the floral appliques. Hang it to dry to keep its shape. And remember, if you're not satisfied, refer to our return policy.
