While her Galliano-designed dress is absolutely stunning, it is a rather safe choice for the risk-taking style icon.
We've decided to bring you a roundup of all the best white looks from the runways, as a helpful comparison. Perhaps Moss should've gone a more wild route with a Viktor & Rolf creation or veered toward the classic in Narciso Rodriguez?
Check out the white ensembles we've selected. And let us know if you like Moss' choice or think she could have gone more daring.
And remember, there's still more Moss-mania to come - her reception dress is designed by Stella McCartney. Could it be one of the paillette options we've selected?
