I ordered 4 of these dresses for flower girls. They came faster than I expected (11 days) and they are perfect. I was worried that they would be too small because I followed the measurement guide, but it was right on the mark. My size 6X/7 daughter is perfect in a size 6 (fits like little girl in picture). It is a slimmer fit, so if your little girl is chunky, you would need to go bigger. I am delighted with the dresses and will be making aqua sashes to match the wedding.
