When the carriage clocks start ticking toward the Order of the Garter service at Windsor Castle, the fashion world basically holds its breath. It’s one of those rare moments where ancient, slightly clunky medieval tradition meets high-end modern tailoring. People talk about the velvet robes and the ostrich plumes—which, let’s be honest, are a lot—but the real focus always shifts to the Garter Day Princess of Wales dress. It’s never just a dress. It’s a strategic move in a very long game of visual diplomacy.
Royal fashion isn't about being trendy. If you’re looking for what’s "in" on a Parisian runway, you’re looking in the wrong place. This is about "stately." It’s about looking at a photo twenty years from now and not cringing at a weird sleeve or a bizarre hemline. Catherine has mastered this. Honestly, she’s turned the Garter Day appearance into a masterclass in how to wear polka dots or monochrome without looking like you’re heading to a 1950s themed garden party.
The Alessandra Rich Era and the Power of the Polka Dot
If we look at the 2023 service, Catherine leaned heavily into a vintage aesthetic that felt like a direct nod to the late 80s. She wore a bespoke white silk dress by Alessandra Rich. It featured a high neck, slightly puffed shoulders, and a delicate black polka dot print. Some critics thought it was too safe. I disagree. When you are standing next to King Charles and Queen Camilla in massive, heavy velvet mantles, you need something that cuts through the visual noise.
The dress was paired with a Philip Treacy hat that looked like a black-and-white saucer, perched at that signature jaunty angle she’s famous for. You’ve probably noticed she sticks to a specific silhouette for these events. It’s almost always a midi length. It always defines the waist. Why? Because the Order of the Garter is held outdoors in the Quadrangle of Windsor Castle. Wind is a factor. A shorter skirt or a flimsy fabric is a wardrobe malfunction waiting to happen, and the Princess of Wales doesn't do wardrobe malfunctions.
Interestingly, the 2023 look was a mirror image of her 2022 choice, which was a vivid "cornflower" blue coat dress by Catherine Walker & Co. The contrast between those two years shows a shift in her role. As the Princess of Wales, she’s moved away from the bright, "look at me" primary colors of her Duchess of Cambridge days and toward a more sophisticated, slightly more muted palette that screams "Future Queen."

Why the Order of the Garter is a Style Minefield
You have to understand the context of the day to appreciate the dress choice. The Order of the Garter is the oldest and most senior Order of Chivalry in Britain. It’s serious business. The Knights and Ladies of the Garter walk in a procession wearing blue velvet robes that weigh a ton. The Princess, however, isn't usually a member of the Order herself (though she likely will be one day), so she watches from the sidelines.
She has to look formal enough to respect the knights, but understated enough not to outshine the actual ceremony. It’s a tightrope.
In 2019, she went with a white coat dress by Catherine Walker with black lace trim. It was very "My Fair Lady." It worked because it provided a clean backdrop for the heavy regalia surrounding her. If she wore a busy floral print, she’d get lost in the sea of velvet and feathers. People often forget that royal dressing is essentially architectural. It's about shapes that stand out against stone castles and ancient chapels.
Small Details That Matter (A Lot)
- The Shoes: She almost always goes for a pointed-toe stiletto. For the polka dot Alessandra Rich dress, she wore two-tone pumps (white with a black toe). It’s a classic Chanel-esque look that elongates the leg.
- The Jewelry: This is where the real history happens. At Garter Day, she often wears the Collingwood Pearl Drop Earrings, which belonged to Princess Diana. It’s a subtle link to the past that fans obsess over.
- The Fabric: You’ll notice the fabrics are always heavy enough to hold their shape. Crepe, wool silk blends, and heavy satins are the favorites. Anything too light would just look messy in a high-resolution photo.
Misconceptions About the "Princess Uniform"
A lot of people think she just picks a dress off a rack and calls it a day. That’s definitely not how it works. Every Garter Day Princess of Wales dress is the result of months of back-and-forth between the Palace and the designers. They have to consider how the dress looks when she’s sitting in a carriage, how it looks when she’s walking up the steps of St. George’s Chapel, and—most importantly—how it looks on a smartphone screen.

There’s this idea that she’s "boring" for repeating silhouettes. But consistency is a brand. When she wears a specific designer like Catherine Walker or Alexander McQueen, she’s supporting British industry. That’s a requirement of the job. You won't see her rocking a trendy new experimental label from New York for an event like this. It’s about heritage.
The "Duchess" vs. "Princess" Style Shift
Looking back at her appearances from ten years ago compared to now, the evolution is pretty striking. Earlier Garter Days saw her in softer colors—pale pinks and creams. She looked lovely, but she looked like a guest. Now, there’s a sharpness to her tailoring. The shoulders are more defined. The hats are larger. She’s occupying more space, figuratively and literally.
In 2014, she wore a light blue Christopher Kane coat dress. It was soft, feminine, and very much in line with her "young royal" vibe. Compare that to the 2023 Alessandra Rich look. The 2023 dress had an edge. It was fashion-forward while remaining deeply traditional. That's the sweet spot she’s found. Honestly, it’s impressive she hasn't run out of ways to wear a coat dress yet.
What This Means for Your Own Wardrobe
You probably aren't attending a chivalric procession at a 900-year-old castle anytime soon. But there are takeaways here. The Princess of Wales uses "uniform dressing" to reduce decision fatigue and ensure she always looks "on-brand."

If you find a silhouette that works—like the midi-length A-line she favors—stick to it. Change the color, change the texture, but keep the bones the same. She also proves that monochrome (sticking to one or two colors) is the easiest way to look expensive. When she paired that white and black dress with a black and white hat, the look became cohesive. It didn't look like she tried too hard, even though we know the planning was intense.
The "Kate Effect" is real, too. When she wears a specific dress, it usually sells out in minutes. But the Alessandra Rich polka dot dress was actually a "repeat" style in a different print, showing that she knows what works and she isn't afraid to stick to a winning formula.
Actionable Steps for Mastering Formal Style
If you're looking to emulate that high-level formal aesthetic for a wedding or a major event, start with the foundation. Get your clothes tailored. The reason the Princess looks so polished isn't just the price tag; it’s the fit. Nothing is too long, nothing is too tight.
Focus on the "three-piece" rule: your outfit, your shoes, and one standout accessory (like a hat or a piece of heirloom jewelry). Keep the colors coordinated to avoid looking cluttered. And finally, consider the environment. If you’re going to be outside, choose fabrics that won’t wrinkle and shoes that won't sink into the grass. That’s basically the secret sauce of the Royal Family’s public appearances.
For those tracking the next Garter Day, keep an eye out for how she handles the transition into more senior roles. We might see even more bold color blocks or perhaps a return to the deep emerald greens she wears so well. Whatever she chooses, you can bet it will be a deliberate mix of historical homage and modern chic.
Look at your own closet and identify your "power silhouette." Once you find the shape that makes you feel like you could handle a royal procession, buy it in two colors. Invest in a pair of high-quality nude or two-tone pumps that go with everything. Stop chasing every micro-trend on TikTok and start building a collection of pieces that feel timeless. That is the real lesson from the Princess of Wales's fashion playbook. It isn't about the dress; it's about the strategy behind it.
