i would NOT go with a dress that "grew on you"

GO WITH THE ONE YOU LOVE!!!!!!!!!!!!!!!! and i agree with restingdonkey, no one will even REMEMBER or CARE that it is a similar style to his ex!!! they are going to be TOOOOOOO busy being in awe of your beauty. and as far as the style is concerned, it is by no means outdated!!! in fact, you will see SO many brides in the pick-up style (your 2nd choice, and personally --- i would prefer standing out and being different!)

good luck on making your decision!!!!
