I went to David's Bridal for my wedding dress a few weeks ago. I was immediately greeted and me and my group were escorted to a dressing room with chairs set up and a little heart sticky note on the door with my name and wedding date (cute!)
The saleswoman (Xeni) was very helpful - especially considering I had no idea what I wanted. She brought me many different dresses until we finally narrowed it down. When I had gotten down to two dresses, she brought out veils and tiaras for me to try and complete the look. When I chose my dress there was a ritual to follow with some kind words from the store manager about my special day and a bell ringing ceremony. A little odd for someone shy like me, but still sweet.
The only downside was having to pay for the entire dress cost up front, but understandable. I liked that when I told her my budget, she did not give me dresses above the cost to try make a bigger sale. Overall I had a great experience!
