AHi everyone! Im making my cousin' s wedding cake. She wants this cake:

Ive covered the top and middle tiers already since both are just styro dummies. After ive covered both tiers, I realized that the fondant turned out ivory instead of white. I didnt add vanilla or other stuff that might alter the color of the fondant. I only have 2 days left before the wedding! Will it be obvious if the cake is not white? Shall I cover the tiers with another layer of fondant? Help!

If the dots are grey in the right tones, I wouldn't worry about it. The focus is the dots, not the fondant underneath.
