Popsugar Fashion The Royals What Will Kate Middleton Wear to the Royal Wedding 2018? Now Obsessing Over: What the Duchess of Cambridge's Going to Wear to the Royal Wedding 18 May 2018 by Morgane Le Caer First Published: 29 March 2018 Image Source: Getty Prince Harry and Meghan Markle's wedding will be here before you know it. While we're excited to discover the bride-to-be's wedding dress, we're also curious to see what the Duchess of Cambridge will choose to wear for the special occasion. It will, after all, be one of the biggest events of the season. Over the years, Kate has attended her fair share of weddings, adhering to a number of different dress codes. However, her brother-in-law's big day will be different for two simple reasons: Kate recently gave birth to her third child, and she'll have to wear a very specific outfit consisting of a day dress and a hat. Considering how perfect she looked for her little sister Pippa's wedding, we have no doubt that Kate will wow us once more, whatever she decides to wear. In fact, we think we might know the kind of outfit the Duchess is going to choose. Ahead, take a look at our predictions.
