Kate Middleton may not be wearing the Queen Mother’s crown just yet, but that hasn’t stopped her from reigning as the royal family’s fashion maven for more than a decade. With an aspirational wardrobe that’s marked by impeccably tailored coat dresses, frocks with mid-length hems in A-line or shift silhouettes, and ever-present heels, the Duchess of Cambridge is always polished and regal—she even looked like a rock star hours after giving birth to her third child, Prince Louis!

Her knack for style should come as no surprise to anyone familiar with her and the Duke of Cambridge’s love story: This is the woman who caught Prince William’s eye while strutting her stuff on the runway, after all. While it would be quite impossible to showcase every one of her sartorial wins throughout the years (and all the times she's famously repeated them), we aimed for the next best thing—33 of the best Kate Middleton fashion moments in history. Keep reading to see all of our favorite looks.

The Duchess of Cambridge was turning heads with her outfits eons before she ever became an official member of the royal family, and this photo from the Sovereign's Parade at the Royal Military Academy Sandhurst certainly proves it—that Giorgio Armani coat is as chic as they come. Rumor has it it's also one she rewore at a later date.

November 10, 2010: The "Kate Effect"

It was the dress that launched a thousand copycats. So iconic was the dark blue Issa wrap dress that Kate famously wore for her engagement announcement to Prince Williams, it marked the beginning of the “Kate effect”—a phenomenon in which whatever the activist wore would instantly sell out. In addition to perfectly setting off her eyes (and that stunning sapphire engagement ring!), it was similar to the blue frock William’s mother, Princess Diana, wore for her own engagement announcement.

What’s the one thing that can top an epic engagement dress? An epic wedding gown, of course! Kate’s certainly delivered, with her Sarah Burton for Alexander McQueen masterpiece going down in history as one of the most gorgeous—and expensive!—royal wedding gowns of all time. The $434,000 creation featured handmade lace appliquéd with hand-cut flowers on ivory silk tulle and full-length sleeves for a classic, timeless silhouette. The 8-foot train, meanwhile, draped beautifully behind her, while the padded hips lent the gown a Victorian feel.

For her reception, Kate donned another Sarah Burton for Alexander McQueen creation: She changed into a silk A-line gown with a sweetheart neckline, which she paired with a cozy cardigan for a layered look.

Five years later, Kate would pull it out of the closet once more for the 2016 Taste of Norfolk, trading her long, sweeping locks in for an elegant updo.

Long before Rihanna was flashing some of the most stylish (and creative!) maternity clothing around, Kate was making pregnancy look good on her own terms—particular in April 2013, when she treated us all to this delightfully affordable polka dot Topshop piece. Unsurprisingly, it reportedly sold out within an hour of her debut of it. The black shoulder shrug was just the icing on the cake.

March 11, 2016: Power Color

Though Kate looks great in blues and greens, which allow her eyes to really pop, we think red just might be her power color. Case in point? This sophisticated scarlett Eponine two-piece. Boasting a nice, fitted waist and not-too-long, not-too-short skirt, it was an ensemble she also deemed worthy of a repeat, busting it out once more a year later.

This swanky red-and-white houndstooth design, as loosely inspired by Will and Harry's mum, was an easy win for Kate, boasting a great fit, a great pattern, and a great midi length. The fact that its designer, Catherine Walker, is also a royal favorite, certainly doesn't hurt, either.

Kate carefully navigated the political fashion waters at the 2018 BAFTA's, where the dress code was all black in honor of #MeToo. Though the Duchess wasn't dressed in the hue, she did choose a muted dark green design that made for a happy compromise. It turned out to be one heck of a chioce: The empire waist did wonders for her then-pregnant silhouette, too!

Alexander McQueen was once again established as the genius behind the Duchess's 2019 State Banquet look. Featuring a tiered, ruffled skirt, a sweetheart neckline, and a full skirt, it could've easily passed for a wedding gown—particularly when paired with the Lover's Knot tiara upon her crown. The finishing touch? A sash symbolizing the Royal Victorian Order (an honor recognizing service to the monarch), which Kate was bestowed with by the Queen for her and William's eight-year anniversary.
