HELP...PLEASE!

I bought my veil at barron's, and he told me it was ivory. He put it against the white, and it was definately ivory.

I just came back from the bridal salon, to try it on with my dress, and it looks slightly different. two of the women told me you couldn't notice, but one said it looked white...

how much does this matter, and will barron's let me exchange? Prob. not...right?

TIA for any help!
