What would you do? Mark on dress

I had my second fitting which went fine. My dress is silk and I noticed a pull in the fabric right in the center on top. The owner said they can probably press it out, but what if they can't? It didn't show up in the pics I took, but my friend who was with me agreed you can see it in person. It wasn't there the first time I went, I'd have noticed that. its small, but like I said right in the center.

I go back the beginning of April, so I'll see if the pressing worked but if it didn't --what do I do?

I guess I just leave it as is and hope people don't see it? Any recourse?

i don't have any suggestions but i just wanted to wish you the best of luck!
