Found my gown at Vera Wang about 2 weeks ago and I am still on cloud nine! The salon is pristine, the service exceptional. Very friendly, warm, and personable people who really know the gowns inside and out. Extremely knowledgable when it comes to what suits your body, what types of alterations you'll need, how the dress will look when its bustled, etc.
I tried on as many gowns as I wanted, no one ever pressured us in terms of time. I had narrowed it down to two gowns, and the consultants had me try each one on again so I could really compare them. With their help and expertise it was clear which one was for me. Once I chose the dress we had so much fun picking out the veil, trying on belts, and other accessories.
I recommend not coming with an "entourage". The setting is very intimate and I imagine it would be overwhelming having a lot of people with you. I went with just my mom and we had the best time.
I had been to White and Kleinfeld a few weeks prior, and had nice experiences there, but they dont come close to Vera Wang. Saved the best for last and it was so worth it.
