Princess Eugenieis known for her daring sense of fashion (she’s certainly not afraid torock an over-the-top fascinator!) and the world be watching as she struts down the biggest runway of her life: that walk down the aisle.
The 28-year-old royal is set to tie the knotfiancé Jack Brooksbankon Oct. 12, and royal fans are anxious for any hint of her bridal look — and how it will compare to the instantly iconic wedding day style of her cousins’ brides,Kate MiddletonandMeghan Markle. Here’s what we know so far.
Designer
Princess Eugenieis following the tradition of putting a designer with ties close to home on a global stage. However, she’s staying mum on exactly who snagged the big job for now.
“I’m not telling anyone who is making it, but I can say it is a British-based designer,” she recently toldBritishVogue. “[The dress] is the one thing that I was really decisive about. As soon as we announced the wedding, I knew the designer, and the look, straight away. I never thought I’d be the one who knew exactly what I like, but I’ve been pretty on top of it.”

Kate famously wedPrince Williamin a custom Sarah Burton for Alexander McQueen gown that featured long lace sleeves and a v-neckline. Since her 2011 wedding, Kate has opted for pieces from the British brand again and again, from evening gowns to skirt suits and coats.
Sleeves
Both Kate and Meghan opted for a ceremony gown with long sleeves, showing that modesty can still be fashion-forward. Of course, not all royals stick to the style —Zara PhillipswedMike Tindallin a dress featuring sheer cap sleeves, and Peter Phillips’ wife Autumn went for a similar design.
There’s also the weather factor — it may be too chilly in Octobernotto opt for long sleeves!

It was reminiscent of Kate’s quick change into a white satin strapless evening gown after her April 2011 wedding. Her glam gown featured a circle skirt and diamante detailing around the waist. She accessorized the look with a simple white shrug.
It’s unknown if Eugenie will follow in their footsteps, but it’s very likely!

Tiara
Royal women aren’t allowed to wear a tiara until their wedding day, and Eugenie will certainly make the most of her first opportunity to do so — after all, we know she loves a good head topper!
The odd-on favorite is the York Diamond Tiara, which her motherSarah “Fergie” Fergusonwore at her wedding toPrince Andrew. The sparkler, which was commissioned especially for Fergie as a gift fromQueen Elizabethfor her wedding, would carry a special meaning for the bride.

Charlie Anderson — former stylist to Eugenie and her older sister, Beatrice — previously told PEOPLEhow the sisters’ closets compare.
Eugenie “tends to like more fitted, 1960s shapes, where as Beatrice likes flounce and floral pieces,” he said. “I think Beatrice has a good eye; she’s been wearing some fabulous pieces over the last few years — she makes daring choices, whereas I think Eugenie is a little more refined in her choices.”
