I had my wedding dress altered by Joanna and it was absolute perfection. I bought my dress at a boutique in Denver. I had a terrible experience with the first alterations place I consulted with, so I spent considerable time researching options near San Ramon online and decided to take it to Joanna's Bridal. Her shop is filled with stunning, beautiful gowns and jewelry (I found some earrings that matched my gown perfectly!) For my gown, she hemmed the bottom of it a bit, took out a layer of the tulle for me and shortened my straps. Everyone on her team was very helpful and responsive, and her rates were very reasonable. She did such an impeccable job -- I have a bridesmaid dress for a wedding next month that I'll be bringing to her also. I would strongly recommend Joanna to anyone in the Tri-Valley area looking for a wedding gown or needing tailoring for a formal event.
