Wedding bells are ringing! Ahead of Prince Harry and Meghan Markle’s royal wedding on Saturday, May 19, Stylish sat down with CNN Royal Commentator Victoria Arbiter to get the details on everything you should and shouldn’t wear to the royal fete. With guests like Priyanka Chopra, Jessica Mulroney, Duchess Kate and Serena Williams expected to attend, the celebration is bound to have some serious #outfitgoals. But, as will all things royal, there are a certain set of rules one must follow when dressing for such a regal affair. That’s why we turned to Arbiter to help Us figure out which styles and accessories get the royal stamp of approval and which are definite fashion faux-pas before the big day. Between fascinators, hats, nude stockings and colorful dresses, we got all the details on what we can expect our favorite stars (and of course Harry and Meghan) to be wearing on their special day.
