Check with Bridal Suite of Bay Shore if you are not too far. I am sure they will help you out with a dress that will come in by the New Year if you order this week. I ordered my dress Sept. 29 and it came in by mid-January. Ask for MaryEllen. Make sure they give you reliable designers that deliver quickly.
GOOD Luck!!
You are still ok, but I wouldn't wait too much longer. I ordered my dress in April for my September wedding and it came in in a month. My friend ordered hers in January for her August wedding and it didn't come in until July! She was panicking!
