Princess Diana Wedding Dress: What Most People Get Wrong

On July 29, 1981, roughly 750 million people glued themselves to their television sets. They wanted to see the fairy tale. What they saw was a 20-year-old girl stepping out of a glass coach in enough silk taffeta to cover a small village.

It was huge.

But honestly, the Princess Diana wedding dress was kinda a mess. At least, that's what designer Elizabeth Emanuel thought the second she saw Diana step onto the pavement at St. Paul’s Cathedral. Elizabeth reportedly felt "faint" because the dress was covered in deep, stubborn creases. The 25-foot train had been folded "like a bedsheet" to fit inside the carriage.

They hadn't accounted for the physics of silk taffeta in a small space.

The Secret Life of "Deborah Cornwall"

Most people think a royal wedding is all posh meetings and tea. For the Emanuels, it was more like a spy movie. To keep the design from leaking, they gave Diana a code name: Deborah Cornwall. Why Cornwall? It was a cheeky nod to one of the titles she’d eventually hold.

Security was intense. They hired two guards, Jim and Bert, to watch the studio 24/7. They even put "decoy" threads and fabric scraps in the trash to throw off journalists who were literally digging through their garbage.

The studio itself was a tiny, cramped attic. Diana loved it there. She’d sneak upstairs to chat with the seamstresses, who were basically in tears every time she walked in. It was her "oasis of peace" in a world that was suddenly obsessed with her waistline.

Speaking of that waist—Diana was struggling.

Between the first fitting and the wedding day, she dropped from a 29-inch waist to a tiny 23 inches. She was battling bulimia, though the world didn't know it yet. The designers had to keep taking the bodice in, eventually making five different versions of it. On the actual morning of the wedding, she literally had to be sewn into the dress.

The 25-Foot "Giggle"

The train is legendary. It’s still the longest in British royal history. But the length wasn't part of some grand royal decree. David and Elizabeth Emanuel just wanted to beat the previous record of 20 feet.

"We found out the longest royal train was 20 foot," David Emanuel later recalled. "I remember giggling to Diana and saying, 'Oh gosh, we've got to beat that!'"

Diana’s response? Basically, "Let’s go for 25."

It wasn't just the train that was overkill. The veil used 153 yards of tulle. The shoes—crafted by Clive Shilton—took six months to make. They had 542 sequins and 132 pearls. Diana was 5’10”, so she was terrified of being taller than Prince Charles. The solution was a flat heel and a hidden tribute: the letters "C" and "D" painted on the arches with a small heart between them.

The "Other" Dress Nobody Saw

One of the wildest secrets of the Princess Diana wedding dress is that there was a spare. A total Plan B.

Elizabeth Emanuel was, in her own words, "neurotic" about something going wrong. What if there was a fire? A theft? A massive ink spill? So, they started a second gown. Diana never even knew it existed. The designers didn't want to worry her.

This backup dress was simpler.

• It didn't have the 25-foot train.
• The silk was white, not the deep ivory of the original.
• The sleeves were more fitted, less "meringue."

Funny thing is, after the wedding, this backup gown just... vanished. Elizabeth says it probably ended up on a sample rail or got torn up for scraps. It’s a ghost in fashion history.

The Perfume Disaster

Seconds before she left for the ceremony, Diana reached for her favorite scent, Quelques Fleurs. Her hand slipped. A huge wet patch appeared right on the front of the skirt.

Her makeup artist, Barbara Daly, told her to just hold that spot of the dress as she walked, making it look like she was just lifting the heavy fabric. If you watch the footage closely, you can see her hand awkwardly tucked over the spot.

Why It Still Matters

Critically, the dress was "too much" for some. Critics called it a "crumpled paper bag" or said it "wore the girl." But for a generation of brides, it was the gold standard. It launched the 80s trend of puff sleeves and massive skirts that lasted a decade.

It wasn't just a garment; it was a costume for a role she was trying to fit into.

If you're looking to channel this era of royal style, don't just look at the lace. Look at the structure. Modern bridal fashion is moving back toward these "theatrical" elements—grand veils and textured fabrics like taffeta are making a huge comeback.

Next steps for fashion history buffs:

1. Research Carrickmacross lace: This is the specific antique lace used on Diana's bodice; it's a centuries-old Irish craft that influenced Kate Middleton's gown decades later.
2. Visit the Althorp Estate: While the dress often moves for exhibitions, the Spencer family home is where the legacy of Diana’s style is most deeply preserved.
3. Compare the "Revenge Dress": Contrast the 1981 wedding gown with the 1994 Christina Stambolian black dress to see the literal evolution of a woman finding her own voice through fabric.
