Ordered my dress yesterday! + question...

I'm so excited! My mom and i went shopping for my dress yesterday...first time out, and first time ever to try on a wedding gown, and I found THE ONE after trying on a few! Its absolutely perfect, and I'm thrilled.

I do have a question...what are your thoughts about sharing details about your dress with people? The women at Bridal Reflections (where we ordered the dress), strongly suggested I not tell anyone about the dress, and my mom agreed. But I don't know if i can be 'that girl'...you know the one...'i want it to be a surprise...' I'm usually the one rolling my eyes at something like this, but now I'm in the situation!!! I caved already and told a couple of close friends about it. But they don't know the designer's name and I couldn't find a photo of it online if I tried, so I think its fine. What do you guys think?
