The Wedding Guest Dress Brands Celebrities Actually Wear, From Designer Splurges to Reformation and ASOS

You received a wedding invitation and saw the two words that can make or break a guest’s experience: dress code. Under it, inscribed in big, swooping letters, is formal, black-tie, or maybe something more nuanced, like garden-party chic (guilty as charged—I made that my own wedding theme).Even for celebrities, wedding dress codes can be difficult to decipher. And while some of us (me) may spend months trying on just-okay dresses in hopes of finding one that fits the vibe, celebs have a few advantages. Namely, their stylists—and okay, maybe their budgets, too.After recently seeing It girls like Taylor Swift and Gigi Hadid show out in jaw-dropping dresses for their friends’ and family members’ nuptials, I figured it was time to peek into the wedding guest shopping habits of Hollywood’s elite.TBH, I expected nothing but custom creations from luxury fashion houses, and while they do love pricier labels like Markarian, Wiederhoeft, and Zimmermann, celebs also reach for contemporary designers and mid-tier brands (they’re just like us!). So, to make the I-do season a little easier, I tracked down a few of the best wedding guest dresses from the brands the famous wedding attendees actually wear — some expected (I too love to wear Reformation to weddings), but some were unexpected and totally new to me.Maria Lucia HohanBefore she was a bride herself, Taylor Swift wore a metallic silk Maria Lucia Hohan gown in Brooklyn with then-fiancé Travis Kelce, and it had wedding guest written all over it. The label is a longtime favorite of hers, and its flowy, pleated silk designs are made for black-tie affairs. Consider it a splurge worth RSVPing yes for.Dôen​If you ever want to crash an upstate, rustic wedding, follow Dakota Johnson’s footsteps and secure a dress from Los Angeles-based brand Dôen. Technically, Lucy, played by Johnson in Materialists, opted for the frilly buttercream dress (and Nike sneakers). But the real takeaway? The label is stacked with nostalgic, wedding-ready designs, ranging from cascading silk to hand-beaded motifs.Deme by Gabriella​Would you believe me if I told you Gigi Hadid wore a $450 dress to her sister’s wedding? Well, she did—and her exact gown is surprisingly still available. Hailing from London-based brand Deme, Hadid’s olive-green Suzie gown is proof that you don’t need to spend a fortune to look your best. Twin with Hadid, or secure showstopping halternecks, caped dresses, and ethereal ruching designed to turn heads.ASOS​Turns out I’m not the only one late-night scrolling on ASOS. Sophie Turner attended a friend’s wedding wearing a—wait for it—$35 poplin halter-neck dress from the online British shop. The lemon-yellow dress has since sold out, but there’s no shortage of drool-worthy options up for grabs.Tove​Bad blood? Not at the Tayvis wedding, where Karlie Kloss arrived in a liquid-gold Tove gown. The contemporary brand has become synonymous with fluid and subtly sexy occasion dresses, delivering a slew of ready-to-wear designs for every type of dress code.ReformationI’ve long turned to Reformation for RSVP-ready dresses—and so has Kaia Gerber, who wore a long-sleeve dress from the brand to a friend’s wedding. It’s hard to ignore the brand’s sustainable, statement-making garments, calling on design elements like flattering ruching, contrast paneling, and flutter sleeves.Mother of AllStars are just like us — they shop at Revolve. Sabrina Carpenter wore a silky butter yellow dress from Mother of All to a 2024 wedding. The brand’s playful wedding guest dresses, including one similar to Carpenter's below, bridge the gap between dressy and youthful.Free People​Olivia Rodrigo performed “Can’t Take My Eyes Off of You” at a wedding back in 2019. For the occasion, she wore a floor-length Free People dress with a halter neck and retro floral pattern. The brand, which is known for its boho vibes, is perfect for outdoor weddings where floaty and ruffly fit the bill.L’AGENCE​L’AGENCE nails occasion dressing, offering elegant and trendy pieces that extend far beyond the big day. For Marc Jacobs’ wedding back in 2019, Gigi Hadid wore a suit with a sheer, sparkly top from the brand. While we’re in full support of going for a jacket and trousers as an alternative, we love the brand’s take on guest dresses too.Ruby Ford-Dunker (McAuliffe) is a fashion and lifestyle journalist featured in Vogue, InStyle, Elle, Who What Wear, Marie Claire, Brides, the New York Post, Business Insider, and more.
