This is the dress code that guests will have to follow at the royal wedding...

The count down is on!

There's just under ONE month to go until Meghan Markle and Prince Harry marry at St George's Chapel at Windsor Castle.

While it's no secret that the royals have plenty of etiquette rules that they have to follow... you can only imagine what the rules are like for the royal wedding.

As printed on their invitations, the couple have instructed male guests to don a uniform, morning coat or lounge suit and the women to be dressed in a day dress with a hat.

Having a hard time deciphering that dress code?

Let us break it down for you...

1. Day dresses
   Dresses that are mostly black or mostly white are no-nos. Garish patterns are also not acceptable. Subtle patterns or bright, vibrant colours are ideal.
   
   Female guests are encouraged to cover their shoulders and opt for designs that are free of cut-outs or sheer details. Absolutely no cleavage should be visible. 
   
   The length should be tasteful, too. That means slightly above or below the knee, or tea length. Hemlines shouldn’t be shorter than the longest finger when arms are held at the side, and no longer than mid-calf.
   
   Another important rule of the queen's is to always have tights on, so it's a fair assumption that all the women in attendance at the chapel and reception will have sheer pantyhose on, at the very least.
   
   
2. Shoes
   Forget open toes and wedges. The Queen isn't a fan of wedged shoes.
   
   Slingbacks are also considered too informal.
   
   Four-inch heels would be the maximum in height.

3. Handbags
   They should be small. Clutches or other handbags that fit easily on laps are good.
   

4. Hats
   Hats must be worn in church. They are mandatory.
   
   Employing the use of giant flowers, feathers and ribbons is a socially-acceptable way to punctuate your joy for the new couple. However, bigger isn’t always better. No huge brims. Nothing too high.
   
   Fascinators, too, are welcome headgear for the royal wedding.

5. Morning suits
   Men should be wearing morning suits. This is a formal and very traditional suit.
   
   A morning coat features a single button and peak lapels — known as coattails, of course - and they often come in grey, navy and black. It’s often paired with striped trousers, a waistcoat, a collared shirt and tie.
   
   The outfit can be accessorised with pocket squares, gloves, a top hat, and—regardless of whether or not you need one—a cane.

  Meghan and Harry will on May 19 at St George's Chapel, Windsor Castle.
