I think the seller did do that because I swear I have this dress and I compared them and they are EXACT right down to the little balls hanging on the dress... I asked the seller. I will let you know what I find out. But I am sure this is what the seller did.
You'r right. Could very well be, but I doubt the seller would ever admit it. Still curious what they're gonna say though!

The only "difference" I see it the more worn bow like seanbutter said.
