In 2018, we not only have Meghan's royal wedding to look forward to but also Princess Eugenie's. She will say her "I dos" to Jack Brooksbank on Oct. 12, 2018. The wedding is expected to take place at St. George's Chapel in Windsor (where Meghan and Prince Harry will also marry), and there are rumours that Ellie Goulding and Mila Kunis will attend. Nothing is absolute, of course, but it's fun speculating who will be there and what Princess Eugenie will wear. The bride has not confirmed a wedding designer, but did say her gown will not feature "meringue shoulders [because] that's a bit unfashionable." If you take a look at her style history though, you might just come up with some ideas of what the princess will look like on her wedding day.
