Kash, I like the first one you posted the best. BUT with that said, I don't think any of these dresses are right for you, the reason I say it is because you would know it the second you put it on. I was in the same boat as you, I was like "this is cute, I guess I could wear something like this" but when I found my dress I knew without a question that it was it. I second guessed my decision because it was more money then I wanted to spend but once I talked to my FI about it I knew it was the one. Keep looking girl, I know the right one is yet to be "tried on"....
BUT how much fun are you having trying on dresses? I miss dress shopping..
