Tiffany NY was fabulous. The girls there were very friendly and helpful and when I had a bridesmaid dress fiasco, they did not hesitate to let me exchange the dresses - even though technically there are no returns once items have been ordered. All the dresses even arrived a couple of weeks early.
I was a little hesitant about ordering my dress from Tiffany Bridal because a woman I had meet had had some problems with them. In the end everything was fine with my dress. I particularly liked that I did not have to book an appointment to peruse their dresses -- there were many bridal shops I never visited because I would have had to make an appointment. The saleswomen at Tiffany were not at all stuffy and genuinely friendly and warm. The only complaint that I have is that the alterations were much more expensive than what I had been told to budget even though they do have a very specific price list on how much each type of alteration costs, which I only saw the day I paid for the alterations. Despite this, it wouldn't have affected the decision on which dress I chose, since I loved the dress I found at Tiffany Bridal and any train would have gotten chopped off anyway.
