paloma blanca #3565 (PICS ADDED!!)

hi girls,

i tried this paloma blanca dress on and really liked it (not sure if it's THE ONE yet, but it's definitely a contender.) sorry, i can't post a pic because of some IE problems... but the style # is 3565, it's the first dress you see when you go to their website: palomablanca.com

now my questions are:
1) what do you think????? do u think it's too informal because of the material??

2) i tried the dress in mocha (light pinkish color), it also comes in champagne and 'natural' (whatever that means). what is natural???

3) do u think mocha would be appropriate? or should i stick to white/ivory?
