Zara Rhinestone Bow Dress XS

Zara Rhinestone Bow Dress in size XS Washed but never used Kindly please look at the last picture for a minor flaw. It has some stain on it. It’s not as visible in person, I think the picture is pronouncing the stain, but it also looks like it’s going to go away when washed. The stain is on the side near the waist. Thank you!
