While she wears many, TikTok seems to think that the coat dress was an off-white color.

In photos, the shade of the dress does look oddly close to white.

Thanks toTiKTok, people are reviving the debate four years after the fact.

There seems to be two distinct camps that she didn’t mean to and that it doesn’t matter.

“But I honestly don’t think it was intentional.”

Other people think that the decision was wrong either way.

“Too close to off-white to be appropriate,” another user writes.

Back in 2011, Kate’s sister,Pippa Middleton, wore a white bridesmaid dress.

First of all, it was confirmed that Kate picked out her sister’s dress.

This case of wearing white to a wedding is definitely an exception.
