Episodic Crescent Moon Garden Button Up Shirt

I sent an email the day I got it. The top part is fine but the part around my hips is too small. I got the button up - would the open neck camp shirt be looser? The website doesn’t give inches at the hip level. I want to return it and get one that fits. Thanks for your help!

I wore my new moon shirt for the first time today. It's comfortable and the sizing is perfect. I've gotten so many compliments about it. A friend who sews commented on how well made it is. A big win!

Looks and feels great! Usually wear a small, got the extra small and it is still plenty roomy
