This doesn’t look good on me..will return

I bought a large and an extra large in this dress. The large fit perfectly up top but the buttons almost popped of once down to my hips and gapping open. The extra large was ok fitting up top but once at the hips again the buttons nearly popped off. The gapping was still there. If you look closely at the smaller model you can tell that the buttons are stretched. It is a really nice dress, with great material, not much stretch. I just wished it fit my curvy hips. I had to return them both.
