HHmmm I think I like 2 and 3 the best! I agree with you that 2 would be just stunning w.o the pickup.
The only thing about number 1 is that is like, THE ML dress of last year. I feel like I see it everywhere and lots of designers are making this dress similarly for a lot cheaper. I don''t know, I think you would look more special and unique in the other 2 dresses.
