Kate Middleton has served us with some of the most fashionable and sophisticated outfits from the royal family in recent years. From her Alexander McQueen wedding gown to channeling Princess Diana more than once, it’s really no surprise that the Princess of Wales is always a best-dressed wedding guest. Though she's known to regularly wear Alexander McQueen, by creative director Sarah Burton, believe it or not, Kate has also worn more reasonably priced looks from brands like Topshop and Whistles.

If you're looking for a sophisticated and chic dress for your upcoming weddings, Kate is the one to turn to for inspiration. And what we love most about her looks is that she isn’t afraid to take risks. Whether it’s a bold pink hue or an elaborate fascinator, she is willing to step outside of the box and embrace her personal style.

Ahead, we’ve put together some of our favorite dresses inspired by her best wedding guest outfits. Scroll on for five of the Princess' best-dressed guest moments, and advice on how to channel the royal looks yourself.

Following Kate Middleton’s nuptials to Prince William, the Princess of Wales's sister, Pippa, had her moment at the alter in May of 2017. And to fulfill her sister-of-the-bride duties, Kate donned a custom-made dress by Sarah Burton. She paired the blush mid-length ensemble with Gianvito Rossi 105 pumps, in Praline suede, and a Jane Taylor hat.    

Best Mini Option: Zimmermann Silk Wrap V Neck Mini Dress

Size: 2-10 | Materials: Silk | Length: Mini

To capture Kate’s soft and feminine aesthetic, shop this Zimmermann wrap dress. While the hemline falls at mid-thigh, the blush color and the banded sleeves make this look akin to Kate’s original bespoke piece. 

For a Formal Wedding: Lulus Blush Pink Dress

Size: XXS-XL | Materials: Polyester | Length: Maxi

For a longer option, we are fans of this blush pink maxi dress. This is especially perfect for a maid-of-honor look, but can also be worn if you’re invited to a more formal wedding. Style with dangling earrings and a neutral heel à la Kate.

Best Off-the-Shoulder: Ted Baker Edenio Off-the-Shoulder Midi Dress

Size: 2-12 | Materials: Polyester | Length: Midi

While this dress differs from Kate’s dress in many ways, the feminine and romantic style emulates her look perfectly. The off-the-shoulder neckline will elegantly show off your décolletage, plus the skirt has a bit of movement making for a younger look.

For Princess Eugenie and Jack Brooksbank's wedding in October of 2018, Kate opted for a more spirited ensemble compared to her past guest outfits. Here, she wears a raspberry-colored Alexander McQueen dress styled with a matching Philip Treacy fascinator. She then finished off the eye-catching look with velvet accessories and—most notably—the Queen’s Diamond Pendant. 

Most On-Trend: Reformation Rita Dress

Size: XS-XL | Materials: Cotton, spandex | Length: Midi

Hot pink happens to be an especially popular color right now (thanks to the rise of Barbiecore) so this Reformation midi is Kate Middleton-approved and on-trend. Like Kate’s dress, this option features a puff sleeve and a high neckline.  

Best Silhouette: Aje Admiration Asymmetric Mini Dress

Size: 4-16 | Materials: Linen, viscose, polyester, cotton | Length: Mini

For a more modern take on Kate’s pink moment, we love this asymmetrical mini dress from Aje. The subtle cutout and exaggerated puff sleeves make for a statement-making look, but the high-neckline and pleated skirt stay true to Kate’s style.  

For a Casual Event: J.Crew Sweetheart Long-Sleeve Mini Dress

Size: 00-24 | Materials: Cotton, viscose | Length: Mini

If you’re attending a more casual wedding, but still want to pull inspiration from Middleton, this J.Crew dress is a fun choice. The puff shoulders mimic the silhouette of Kate's dress, but the sweetheart neckline and skater skirt make for a more casual take on the royal look.

We already know Kate Middleton is a style icon amongst the royal family, so it’s no surprise that she sported several chic maternity dresses throughout her pregnancies. The most shocking part of this look, though, is that it’s actually completely affordable—the Princess's polka-dot maternity dress is from Topshop! Unfortunately, the mini is no longer available, but we found a few great alternatives we could see Kate loving.     

For a Backyard Event: River Island Black Polka Dot Cut-Out Mini Dress

Size: 6-18 | Materials: Polyester | Length: Mini 

This mini dress keeps the same style as Kate’s look, but it also has a cutout on the back. To make the dress more ceremony-appropriate, style with a black blazer which can be taken off during the reception.

Best Maternity Option: Hatch The Tori Wrap Dress

Size: 0-4 | Materials: Rayon, nylon | Length: Tea-length

Keeping with the maternity theme, this polka-dot dress from Hatch is just as comfortable as it is fashionable. Dress it up or down depending on the wedding dress code, and pair it with comfortable heels or wedges.   

Best Embellishments : Saloni Jamie Short Dress

Size: 0-14 | Materials: Silk, polyester | Length: Mini 

While this is much more of a splurge than Kate’s dress—shockingly —it does put a fun twist on the more conservative look. No need for heavy accessories, the bead and crystal bows are the centerpiece of this mini masterpiece.

It really doesn’t get more regal than this coat dress Kate wore to a wedding in 2011, the same year she married Prince William. The sophisticated gold brocade dress is from DAY Birger et Mikkelsen, and was accessorized with a unique Gina Foster Millinery hat and LK Bennett Sledge heels.

Best Coat Dress: Teri Jon by Rickie Freeman Metallic Jacket Dress

Size: 2-22 | Materials: Polyester, metallic | Length: Below the knee 

If you like the idea of a coat dress, this option from Teri Jon by Rickie Freeman is an almost perfect dupe. While the buttons are concealed in the front, it instead features a dramatic bow tie waist making for a more youthful take on the formal dress. 

Best Long-Sleeve Option: Kobi Halperin Leah A-Line Dress

Size: XS-XXL | Materials: Silk, polyester | Length: Mini

Pulling from the gold brocade pattern aesthetic, we think this A-line mini is a fun take on the look. If you're hoping to keep things sophisticated, style the dress with nude heels and a simple clutch.  

For a Black-Tie Wedding: Teri Jon by Rickie Freeman Metallic Jacquard A-Line Dress

For a black-tie wedding, you can’t go wrong with this glamorous and elegant jacquard cocktail dress. While you won’t be upstaging the bride, you are sure to feel like royalty when you slip into this number.

If you’re in need of some coat inspiration for winter or early spring weddings, Kate has you covered. She wore this M Missoni coat to Lucy Meade and Charlie Budgett's nuptials in March of 2014. Under the coat, she sported a Whistles blue patterned dress and also accessorized with gold jewelry.

Best Tea-Length: Whistles Brushed Geo Dobby Dress

Size: 0-16 | Materials: Recycled polyester | Length: Midi

Taking inspiration from the blue color of Kate’s coat, this Whistles dress is perfect for a cocktail attire wedding. The brand is a favorite of the Princess, so we have a feeling this dress would get her seal of approval.

Best Winter Coat: J.Crew Petite Wool-Blend Lady Coat

As for what to wear on top, this J.Crew dress coat is certainly a winner. Try out a monochrome look with a matching dress or pair with a printed blue dress as Kate did.
