At long last, we鈥檙e finally getting closer to Prince Harry and Meghan Markle鈥檚 royal wedding, and we couldn鈥檛 be more excited. And while we鈥檙e obviously dying to see Markle鈥檚 wedding dress聽for her big day, we kinda can鈥檛 help but wonder what guests to the royal wedding are supposed to wear鈥 especially given all the royal style rules.

Even though the bride-to-be has broken all kinds of royal fashion protocol, from her California cool girl messy buns to her sheer engagement gown, guests at the couple鈥檚 wedding would surely never want to break any kind of sartorial expectations. But, surprisingly, it turns out that royal wedding dress codes aren鈥檛 all that different than regular weddings, according to an expert.

Us Weekly chatted with CNN royal commentator Victoria Arbiter about what guidelines guests at Harry and Meghan鈥檚 wedding should abide by, and they sound pretty close to what most of us would wear at a typical summer wedding. Since it鈥檚 a daytime affair, Arbiter says, 鈥淭here are a lot of maxi dresses and sundresses that are long and are very in this year, so we might see some of that,鈥 but we likely won鈥檛 see any formal evening attire, as Arbiter points out, 鈥渋t鈥檚 just not appropriate for a daytime wedding.鈥

If guests are opting for a shorter dress, it seems stockings aren鈥檛 required these days鈥 but not flashing any undergarments or shoulders in the chapel is. As far as colors and patterns, Arbiter expects to see 鈥渓ots of floral prints鈥 and bright colors, with men in a 鈥渕orning suit,鈥 which is 鈥渁 formal set of clothes including a long black or grey coat, striped trousers, and a top hat.鈥 If they鈥檝e served in the armed forces, men will likely wear their uniform.

A few off-limits colors? Black, which is considered a 鈥渇uneral color,鈥 and white, which could 鈥渟teal the bride鈥檚 thunder.鈥 Royals, they鈥檙e just like us!

Of course, hats are appropriate for women to 鈥渕ake the outfit that much more special鈥 have some fun and wear something that on a normal day they don鈥檛 have an opportunity to wear,鈥 but a tiara is a no-go鈥 unless you鈥檙e the bride, of course.

With famous attendees including the Spice Girls, Priyanka Chopra, and Serena Williams, we can鈥檛 wait to see what style statements all attendees make on the couple鈥檚 big day.
