I actually just posted this on another dress forum, and just saw this one, too...
I ended up going with something more formal than I had thought I wanted, but it's still flowy and beachy. When I put it on, I just loved it and felt comfortable. I, personally, am not a fan of satin, so I knew I didn't want to go that route. Also, I have a large chest, so I knew I didn't want strapless. This dress has a nice little train too. I also have a mid-length veil with subtle silver beading along the edge and the flower clip for my hair (the beading and stitching is more silver in person). (I have long hair but I plan to wear it back in a loose bun of some sort.) Then I have my glitter shoes (!!!!), which I'll be wearing for the reception.
The short dress is my "back-up" dress. I am trying to be realistic in thinking that I might get overheated being in my dress for 6+ hours, so I wanted to get a cute white dress that I could change into, if need be, and still look like the bride. This one was very reasonably priced, so it was worth it to me to at least have it. I might get a glitzy belt/sash for it.
