We used Bella Bridesmaid for the bridesmaids dresses for our wedding. What a great experience. We had a TERRIBLE experience at another bridesmaids dress store in San Francisco - Bella was such a nice contrast. We found the dresses at the other store but the customer service was so terrible that we didn't want to order them there, keep working with them, and give them our business... so we found the same dresses at Bella and ordered them through Bella.
Only thing to know is that Bella does not do alterations. This wasn't a problem for us - the girls picked up their dresses (or Bella shipped the dresses directly to the out of town girls!) and they got the alterations done elsewhere.
