Girl, don't go get a new dress! You have to remember how "men are" He caught a glimps like you said, and although you feel like he totally saw it, he will not remember what it looks like in a few days. It was a quick picture, and it was on the computer. I really wouldn't worry about it. I have my dress hanging in our closet and although you can "see" it, you can not tell at all what it will look like on. As a man, he saw his sexy FI in a "white dress" and that's it. It will be 100% special when you walk down the aisle, and NOTHING will do justice to the first time he sees you in person alllll done up, walking down the aisle with a smile on your face! Don't worry one bit!
