It is a specific kind of image that flashes across the news every time there is a major royal event. You know the one. He’s standing on the balcony of Buckingham Palace, or perhaps walking with a measured, somber gait behind a casket. Prince William in uniform isn't just a fashion choice or a requirement of the job; it is a visual language that most people completely misread. Honestly, if you aren't a vexillologist or a military historian, you're probably missing about 90% of what his chest full of medals is actually saying.
He looks sharp. Obviously. But for William, the uniform is a weird, complex blend of personal history and constitutional duty.
The Weight of the Blue and Red
People often ask why he wears different things for different days. It’s not about what looks best with his complexion. It’s about "orders of dress." When you see the Prince of Wales in that deep navy RAF (Royal Air Force) uniform, it’s a nod to his time as a Search and Rescue pilot at RAF Valley in Anglesey. That wasn't a "fake" job. He spent over three years flying Sea King helicopters, often in brutal conditions over the Irish Sea.
Then there’s the red. The iconic tunic.
When he wore the bright red uniform of the Irish Guards for his 2011 wedding to Catherine Middleton, it was a massive statement. At the time, he was the Colonel of the Irish Guards. It’s a role that carries significant weight within the British Army. But things change. Since his father became King, William’s military roles have shifted. He is now the Colonel of the Welsh Guards. This means the buttons on his tunic are now arranged in specific clusters of five—a tiny detail that signifies the 1st Battalion, Welsh Guards. If you see him in a red tunic today, look at the buttons. That's how you tell which "William" you're looking at.
Medals: Service vs. Commemoration
There is a common misconception that every medal on a royal’s chest is for "valor" in the traditional sense of a Hollywood movie. It’s more nuanced than that. If you look closely at Prince William in uniform, you’ll see a specific row of honors.
He has the Queen’s Golden, Diamond, and Platinum Jubilee medals. These are commemorative. Everyone serving in the Armed Forces for a specific amount of time during those years received them. However, he also wears his wings. Those RAF wings on his left breast were earned. He did the grueling training. He logged the hours. To the military community, those wings carry far more "street cred" than the shiny gold discs next to them.
He’s also a Knight of the Garter. You’ll see this signified by the garter star on his chest and, occasionally, that heavy, dark blue velvet mantle that looks like it weighs fifty pounds. Because it probably does.
The Controversy of the "Missing" Uniform
Remember the funeral of Queen Elizabeth II? Or the Coronation? There was so much chatter about who was in uniform and who wasn't. For William, there was never a question. As a working royal and a future King, his identity is inextricably linked to the military.

But there’s a burden there.
Every time he puts on the uniform, he is representing the state. He isn't just William; he's the embodiment of the British Armed Forces' relationship with the Crown. It’s formal. It’s rigid. It’s a far cry from the videos we see of him playing polo or dropping into a youth center in a sweater.
What People Get Wrong About the Sword
Sometimes he carries a sword. Sometimes he doesn't. This isn't random. It depends on the specific "order of dress" (No. 1 Dress vs. No. 2 Dress). The sword is the 1897 Pattern Infantry Officer's Sword. It’s a symbol of his commission. When he’s in the RAF blues, the sword pattern changes.
The complexity is staggering. Think about it. You have to remember which way the medals are pinned, which sash goes over which shoulder (the Garter sash is blue, the Order of the Thistle is green), and which hat matches the venue. He has a team to help, sure, but he’s the one who has to wear it with a straight face while the world’s cameras are zoomed in on his lapels.
The Shift to "The Prince of Wales"
Since 2022, the way we see Prince William in uniform has evolved. He has taken on more honorary appointments. He is now the Colonel-in-Chief of the Army Air Corps. This was a big deal—taking over a role previously associated with his father and, in some ways, his brother.
The uniform is his armor.
When he’s at the Cenotaph on Remembrance Sunday, the coat is heavy, charcoal gray, and austere. There are no bright colors there. It’s about the solemnity of the moment. The way he salutes—sharp, palm out in the British style—is something he’s been doing since his days at Sandhurst. He entered the Royal Military Academy Sandhurst in 2006 as an officer cadet. He was "Officer Cadet Wales." That’s where the foundation was laid.
Decoding the Aiguillettes
Ever noticed those gold braided cords hanging from his shoulder? Those are called aiguillettes. They aren't just fancy rope. They signify his role as an Aide-de-Camp to the Sovereign. Originally, these cords were used by aides to hold pens or tools for their generals, but now they are purely symbolic of a close, trusted relationship with the King.

William wears them on his right shoulder. It’s a subtle nod to his position in the hierarchy. You won't see them on everyone.
The Practical Side of the Pageantry
Being Prince William in uniform also means dealing with the physical reality of the gear. These uniforms are often made of heavy wool. They are designed for 19th-century aesthetics, not 21st-century comfort. Standing for two hours in the sun during Trooping the Colour in a bearskin hat and a wool tunic is an endurance test.
He’s had to learn the "guardsman's lean"—essentially how to stand without locking your knees so you don't faint. It’s happened to the best of them.
Why It Matters for the Future
As William moves closer to the throne, the uniform becomes less about his past service in the RAF and more about his future as the Head of the Armed Forces. When he becomes King, he will technically be the "Source of Honor."
Basically, the uniform is a bridge.
It connects the 23-year-old kid at Sandhurst to the 40-something father of three to the future monarch. It’s the most consistent visual thread in his life.
How to Spot the Details Yourself
If you want to look at the next royal event like a pro, keep a few things in mind.
First, check the cap badge. It will tell you which branch he’s representing at that exact moment. Second, look at the "cypher" on the shoulder straps. Since the King’s accession, many of these have changed from "EIIR" (Elizabeth II Regina) to "CIIIR" (Charles III Rex).

Third, pay attention to the sash. If he’s in Scotland, it might be the green sash of the Order of the Thistle. In London, it’s almost always the blue of the Garter.
Identifying the Military Roles
To understand the full scope of his service and honorary positions, you have to look at the timeline. It’s not just one uniform; it’s a wardrobe of various regiments.
- The Blues and Royals: This was his home regiment when he first commissioned. You'll often see him in the dark navy tunic with red accents associated with the Cavalry.
- Royal Air Force: The light blue-grey. This is where he spent his most active years of service. It’s arguably the uniform he feels most "himself" in, given his passion for flying.
- The Welsh Guards: His current primary regimental focus as Colonel. The leek symbol on the collar is the giveaway here.
It is easy to dismiss the regalia as "costume." But for the people serving in those regiments, having the Prince of Wales wear their specific buttons and their specific badge is a massive point of pride. It’s a connection between the barracks and the palace that has existed for centuries.
The Actionable Insight for History Buffs
If you’re trying to track the history of the monarchy through dress, start by following the Court Circular. It’s the official record of what the royals do. When you see a notice about a "Review of the Troops," look up the specific uniform William wore.
You can actually learn a lot about British geopolitics just by watching which uniform a royal chooses for a state visit. If he’s visiting a naval base, he’s in the Navy blues. If he’s at a parade for the Irish Guards, he’s back in the red.
Next time you see a photo of the Prince, don't just look at the smile. Look at the cuffs. Look at the medals. Look at the way the cap is tilted. There is a whole biography written in that thread and gold lace.
The best way to stay informed about these changes is to follow the official Royal Family social media channels or the Ministry of Defence updates, which often explain the significance of the military appointments. Understanding the distinction between "earned" service medals and "honorary" appointments provides a much clearer picture of the Prince's actual military career versus his ceremonial duties. Look for the "C" (for King Charles) or "ER" (for Queen Elizabeth) on the buttons to see how the transition of the monarchy is physically manifesting in the Prince’s wardrobe. Over the next few years, as more regimental badges are updated to reflect the new reign, William’s uniform will continue to be a living map of the UK’s history.
