Now, it seems a pub a stone's throw from St. George's Chapel in Windsor is following suit-with a commemorative royal wedding gin!
The invitation says: "His Royal Highness The Prince of Wales K.G., K.T. requests the pleasure of the company of (name) at the marriage of His Royal Highness Prince Henry of Wales with Ms. Meghan Markle at St George's Chapel, Windsor Castle on Saturday 19th May 2018 at 12 noon followed by a reception at Windsor Castle". "More than 250 members of the Armed Forces will perform ceremonial duties at the wedding".
Assistant Chief Constable David Hardcastle, strategic commander for the wedding, said: "We are proud to police the Royal Borough of Windsor and Maidenhead".
According to People, the streets within the precincts of the castle will be lined by members of the Windsor Castle Guard from 1 Battalion Irish Guards.
The Band of the Irish Guards is also expected to play some songs at the couple's wedding.
Harry has served with British army regiments and worked with various units like the Royal Marines, Royal Navy Small Ships and Diving, 3 Regiment Army Air Corps and The Royal Gurkha Rifles.
Thames Valley Police also announced a raft of security measures already in place, including road barriers and number-plate-recognition technology ahead of the big day.
Air Chief Marshal Sir Stuart Peach, chief of the defense staff, also released a statement following the palace's announcement.
Prince Harry joined The Blues and Royals in April 2006, serving with the Household Cavalry Regiment.
"I am particularly pleased to hear that members of the Armed Forces who have a close relationship with Prince Harry will be taking part", he added.
The military clearly holds a huge place in Prince Harry's heart since he served in the Army for 10 years, where he rose to the rank of Captain and did two tours in Afghanistan. He continues to work with the veteran community through organisations such as the Invictus Games and Heads Together.
