See all of Duchess Kate's best wedding guest looks

With the wedding of Princess Eugenie and Jack Brooksbank happening this Friday, we can't wait to watch all of the royal festivities unfold.

From the untraditional cake to the roles that Prince George and Princess Charlotte will play, a lot of details surrounding the big day have already been revealed. But one thing that we will have to wait to see until Friday morning is what Duchess Kate will be wearing!

And since Kate is one of our favorite style icons, we are looking back at all of her best wedding guest outfits from even her pre-duchess days. From the stunning blue coat that she wore to the wedding of Lucy Meade and Charlie Budgett in 2014 to the dusty pink draped dress that she wore at her sister Pippa's 2017 nuptials to the cream ensemble that she wore in May to Prince Harry and Duchess Meghan's wedding, it's hard to pick a favorite look of hers.

Scroll through the gallery above to see Kate's best wedding guest looks and check back here on Friday to see what she wears to Princess Eugenie's wedding!
