Finally! I had gone over the Davids Bridal, just to see if there was something there I liked so I would have a back up plan. Then, when myappointment there was over, it occurred to me that my bridal salon was really close by, so I should just go there. Apparently my dress had arrived that morning, and it just so happened that their alterations lady had an opening 30 minutes after I got to their shop.
.::Phew::. They don't have to make any alterations, just putting in a bustle, and putting in the corset back (they weren't able to order one that came with a corset back unless I was willing for it to come in 2 days after the wedding... ummm... no.) So they're paying for the cost of the corset to be put in. My next appointment (and hopefully, my last) will be July 9th... 4 days before the wedding on the 13th. It's a time crunch, but it's better than nothing!
