Well after two full weekends of shopping over the past few months my mother and I finally found her a dress this past weekend! Hooray! My mother is petite and very fashionable but has her own style. It would just not do to have her in a typical "mother of the bride" outfit. We went to every department store in NYC and finally found "the dress" at Bergdorff Goodman (on sale thank goodness). I only have a quick shot of her in the dress with a camera phone -- I promise to take more later.

I wish I was more help, but my mother doesn't shop on line. She hates shopping at all really so it was a challenge to even get her to stop being cranky long enough to get in and out of options! But we finally did it :)
Was this a difficult task for you too? Anyone else with lovely petite fashionable mothers? Where did you get your dress? Feel free to post pictures to share to help others with this!
