Even though this will be Meghan’s second marriage and most women can choose not to wear white if its not their first wedding, royal rules dictate that all brides must wear white regardless. The well-known tradition first started with Queen Victoria in 1840.

All royals must take a formal wedding portrait following their nuptials. Since Prince Harry and Meghan Markle’s wedding will take place in May and Kate Middleton’s baby is due in April, will the new royal baby make it into the portrait? We can’t wait to see!

If there’s a wedding card print that Meghan has her heart set on, she can forget about it. The Queen will send out gold-embossed invitations to people on the guest list, which will be appropriately formal. 1,900 invitations went out to Will and Kate’s wedding guests in 2011.

Male guests are expected to wear military uniforms, morning dress (single-breasted coats with tails) or lounge suits (what we consider a business suit). Female attire is less specifically outlined, though hats are a must.

Will and Kate’s reception included two cakes, which is the norm at all royal weddings: one multi-tiered fruitcake (the traditional royal wedding choice) and one chocolate biscuit cake (at the request of Will). We already know Harry and Megs have their heart set on a lemon and elderflower concoction!

When Queen Victoria married Prince Albert in 1840, she carried myrtle — known as the herb of love — in her bouquet. After the wedding, Victoria planted a myrtle shrub in her garden at the Osborne House on the Isle of Wight. Every British royal bride since has carried a bouquet containing a sprig plucked from the same shrub.

Of course, there is a very long history of royal brides wearing tiara bling in their hair on their wedding days. But as a self-proclaimed feminist, will Meghan be swayed by the sparkly beauty of all those tiaras, or will she stick to her guns and rock her own wedding day style?

Luckily for Meghan, yellow gold is already her favourite because all of the royal women’s wedding bands have contained precious Welsh gold from the same nugget mined in Dolgellau, North Wales — a variety of gold that’s three times more valuable than gold from Australia or South Africa.

Members of the Royal Family take a new name when they’re married. As with Kate, the wife of a prince will get the title princess up on marriage, however, the husband of a princess will not be called a prince.

According to the Royal Marriages Act of 1772, royal descendants must seek the monarch’s approval before proposing. Luckily for Meghan, the Monarch and her husband, Prince Philip, both seem taken with her. So she probably won’t have any problems in this department.

Every Royal wedding party must include a crop of children. In letting their children take part in Pippa Middleton’s recent nuptials, the Duke and Duchess of Cambridge continued a long tradition of having Windsors as bridesmaids and pageboys – even if it’s usually at the weddings of others.

This one’s a weird one but Meghan will have to follow the proper specifics when she dons a tiara on her wedding day. Although tiaras were traditionally worn towards the front of the head, the modern style is worn farther back on the head at a 45-degree angle.

Whoever Meghan’s wedding dress designer will be on the day of her nuptials, he or she has a strict rule to adhere to: No cleavage! Cleavage isn’t a part of the Royal dress code and Princess Diana reportedly used her clutches as a way to hide her cleavage when exiting a car.

Sorry bridesmaids but this is one tradition that won’t be making the jump across the pond. The bride leaves her bouquet at the grave of the “Unknown Warrior”, which is a spot in Westminister Abbey where all brides since the late Queen Mother have left their bouquets following the wedding.

The Royal wedding dress is typically made out of lace. While Kate Middleton’s dress was designed by Sarah Burton and Princess Diana’s dress was designed by Elizabeth Emanuel, both incorporated lace detailing in the designs so Meghan better get used to this fabric because she will have to wear it in some form or another.
