I like #1, BY FAR the best. It seems like it isn''t trying as hard to be beautiful, it just is. And I love the gorgeous details. #2 just looks like too much material...it takes you over, and I always think a dress should highlight you. #3 is my second favorite. But #1 wins for me...it is classy and organic and lets you shine through.
I love #1 and #3. They are the most flattering. #2 just looks a bit big and with too much material bunched up around the waist. #3 is VERY unique in the structure of the bust/torso. I like unique #1 is very flattering on your and very feminine.
