Meghan Markle’s no stranger to royal weddings. Obviously. After she married Prince Harry, she went to the wedding of his cousin, Celia McCorquodale, where she wore an Oscar de la Renta dress. A few months later, she was spotted in a Club Monaco ensemble at the wedding of Harry’s childhood best friend, Charlie van Straubenzee and Daisy Jenks. Both outfits were colourful, bold and effortless. They were a breath of fresh air, different to the stiff coat dresses we usually see at royal ceremonies.

Given Meghan’s sometimes unconventional yet stylish choices, we’re all wondering what she’ll wear to Princess Eugenie’s wedding on October 12th. The ceremony will be held at St George’s Chapel at Windsor Castle (the same place where Meghan and Harry wed) and is expected to be a huge celebration.

Meghan’s winning wedding outfits so far:

Since the church ceremony is a little more formal, my guess is that Meghan won’t be wearing a fluttery, floral dress, as she has done for the summer weddings. Kate Middleton is likely to be in a coat dress. If Meghan chooses a breezy gown, it might come across as too casual for Princess Eugenie’s wedding.

On 16 June, Meghan Markle and Prince Harry attended the wedding of his cousin Celia McCorquodale in Stoke Rochford, Lincolnshire. Meghan wore a beautiful blue-and-white Oscar de la Renta dress with a pair of Aquazzura shoes. The same pair she wore to her own wedding reception.

On 4 August, Prince Harry and Meghan Markle attended the wedding of Charlie van Straubenzee. For the celebration, the Duchess of Sussex wore a multicoloured Club Monaco dress and her Aquazzura bow pumps. She topped it off with a navy Philip Treacy fascinator.

This time, she is likely to go a different route, with more sophisticated styles such as this fit-and-flare Roland Mouret number, the same one Jennifer Garner wore to her walk of fame ceremony. To not steal the spotlight from the bride, Meghan might also choose a more demure colour to wear, such as navy, pale pink or caramel.

On 9 July, Meghan Markle and Prince Harry attended Prince Louis’ christening at Chapel Royal at St James’s Palace. Meghan wore a Ralph Lauren dress and a Stephen Jones hat while Harry wore a blue suit. Meghan’s look was simple and elegant. The colour  – though a little unexpected – looked gorgeous on her.

Which designer will she choose?

As for who might design Meghan’s wedding guest look, the possibilities are endless. She has worn creations from Stella McCartney, Carolina Herrera, Prada, Altuzarra, and, of course: Givenchy. As Elle has noted, Meghan has worn the label to most of her firsts as a royal, so she could wear the fashion house again to one of the biggest wedding days in history. One thing we know for sure, however, is that Meghan will most definitely have a fascinator, as guests are required to wear them to royal weddings.
