To dress your little one in this beautiful flower girl dress, first, make sure to measure her accurately using the size chart we provided. Once you've received the dress, help her step into it gently through the top. Adjust the dress so it sits comfortably on her shoulders and waist. When it comes to washing, it's best to hand - wash the dress in cold water with a mild detergent. This will help preserve the delicate lace and tulle fabric. Avoid using harsh chemicals or bleach as they can damage the fabric and the color. After washing, gently squeeze out the excess water and lay the dress flat to dry. Don't hang it as it may stretch the fabric. When not in use, store the dress in a cool, dry place. You can use a garment bag to protect it from dust and dirt. Also, remember that our child sizes are not based on age or height, so always refer to the size chart for the perfect fit.
