Also op if you're this undecided I think it just means you haven't found the right dress
This is true. Both dresses are beautiful from the back and you have a beautiful figure, but they both let you down on the bust area. The first one you would need serious architecture to pull it off; it's just not a great cut and the second one suits you better but again it looks a bit off (maybe with good alterations?) and some detail added to it. Would you consider a different neckline, like a corset, square, rounded neckline with boning?
