As soon as Buckingham Palace announced that Princess Eugenie had gotten engaged to her longtime boyfriend Jack Brooksbank [1], we started wondering about what her wedding dress would look like. With the ceremony taking place in Autumn at St. George's Chapel in Windsor — which is also where Prince Harry and Meghan Markle chose to tie the knot [2] — she may decide to take inspiration from the royal brides before her [3], or simply let the season inspire the design of her gown.

While we don't know who she'll wear on her big day, we do know that there are a few royal rules to follow [4]. With this in mind, it's possible that Eugenie will turn to a fashion house that the royals love to wear [5]. Who knows, she might even take a page out of the Duchess of Cambridge's book and wear a feminine Alexander McQueen gown [6]. But one thing's for sure: regardless of who she wears on her wedding day, Eugenie's dress will surprise you. Read on to discover some of our dress predictions, and take a closer look at her stunning engagement ring [7].
