Here's a few more great tips from How 2 I Do on how to Marry like a Royal...
- Make sure that as the Bride or Groom you are not responsible for doing anything on the day - delegate tasks to your Best Man, ushers and Bridesmaids and make sure they have contact details for key suppliers
- The Royal Wedding may be rainy. Have a clear contingency plan for wet weather such as big umbrellas and an indoor photo and drinks reception location
- Plan timings with precision and make sure you know how long it will take to drive to the wedding venues, how long the speeches will be and how long the photos will take
- You may not be marrying a real Prince but make sure you feel like a Princess and be sure to have all of your beauty essentials on hand to be "close up" ready at all times
- You don't need to follow Royal protocol but brush up on Wedding etiquette such as how the top table should be laid out and in which order the speeches should take place (Father of the Bride, Groom and then Best Man)
- Why not take inspiration and go for a Cool Britannia theme with lots of Union Jack Bunting and a street party style reception
- Prince William will be having a special chocolate biscuit cake so why have fruit cake if you don't like it or for more variety have tiers with different cake flavours
- Kate Middleton has a very individual look and likes to be perfectly groomed and stylish rather than cutting edge fashionable. Make sure that your wedding look reflects your personal style so that you are a highly groomed version of yourself.
