Final update: Unfortunately, the alterations were not adequate and we had to take the dress to another seamstress in our own town. Luckily, my daughter was able to get here earlier than expected, so we had time to have the dress re-altered. I know that had we lived in Phoenix, Addy would have fixed the dress to perfection, but circumstances would not allow that.
After the wedding, I contacted Addy's Bridal to inform them about the dress not fitting and what we had to do to fix it. Addy was understanding and informed me that wedding dress alterations are not always perfect the first time and that several visits may be necessary before the dress is correct. Addy and I did come to an agreement and I will say that I am appreciative for her quick response and the remedy that was reached.
If you learned anything from our experience, it is that if you are buying your dress in a different city than where you reside, it would be best for you to find a seamstress in your local area so that you don't have the same issue we did!
