I'm another Maggie bride.
It was a toss up between that one and a gorgeous Stephanie Allin. I prefered the SA if I'm honest, but it was far too similar to our friends dress. We were at her wedding earlier this year, and she will be one of only 4 people at our wedding next year - it just felt a bit too copy cat and unoriginal to be a go-er.
I never went looking for a particular designer, although I did want to see specific dresses IYSWIM. Unfortunately, there's not all that much choice round here, or at least not for the designers whose dresses I liked online and wanted to try.
