The purple really sticks out to me. Especially the top-right flower. That would be my choice.
I suggest purple too. It's one of the more "girly" colors from the dress. Also, the first color I noticed!
I would vote for the green.
I vote for green as well!
I would go with the light sage green so that all of your fondant pieces 'pop'...if you do purple it will dominate the entire cake...
I vote green too.
I would suggest green since purple would stand out and over power the rest of the colors.
I also like the green and think it will make the flowers pop. Looks like it's going to be a really cute cake.
I vote green too . . . And i want that frock! sooo cute! wonder if they come in adult sizes . . . XD
Odd one out... I vote white to make all the colors pop, even green and purple
I would also go with white, maybe with green ribbon around the cake if the design allows.
My first thought was green when I looked at it. It's a bit more neutral, allowing the other girlie colors to stand out well.
Another odd one out, my first thought was black and then using all the other colors on top. Then I thought white...
