I love them all, but really like #1 - maybe because it's Amy Butler? I adore her fabrics, and some of the dresses I have seen of hers are AMAZING! I think the pattern you picked plus that fabric would be gorgeous.
I think because the dress has a high neck and a lot of space on it for a pattern, I like the idea of a big airy print, like the palm tree one they used. So my vote is for #1.
I would prefer the other prints on skirts, tanks, strapless dresses... but not as much of it, if that makes sense.
