I went dress shopping today, and really loved 2 dresses.
http://www.allurebridals.com/index.php?id=3&product_id=192This one is very light weight and comfortable. And it is cheaper of the two.
http://www.allurebridals.com/index.php?id=3&product_id=694This one photographed better. But, it was really heavy and I kept pulling it up. I realize it was a sample dress that was really too big, and that it would have a lot less fabric on my own, but I worry that it will still fall down. Oh, and it was about $800 more. The model is also a little creepy looking in this picture.
And I also found this bridesmaid dress... in red
