The Most Iconic Christian Siriano Outfits Celebs Have Rocked On The Red Carpet

Finding fame through reality TV is now the norm for musicians, models, dancers, and even entrepreneurs, but it's rare that we get to witness the complete rise of a fashion designer. Christian Siriano stands out from many of his contemporaries, building his brand from the ground up after winning the fourth season of "Project Runway." Launching his first label a year later, he's been making waves in Hollywood ever since. All of his looks have a certain flair, but some are simply impossible to forget. 

If the designer's style can be summed up, it would be structural and glamorous, not afraid to take risks but also not trying too hard to achieve a shock factor. Siriano explores the classic and the trendy alike; for instance, he debated the merits of Barbiecore in an exclusive interview with Glam back in 2023. Dressing everyone from Michelle Obama to Oprah over the years, he does a flawless pantsuit just as well as he does a boundary-pushing Met Gala frock. His most iconic red-carpet outfits are recognized by fashion experts at the time they're worn, and still have fans (and the press) gawking years later.

One of Siriano's most admirable qualities, especially in the fashion industry, is his enthusiasm for dressing everyone, no matter who they are or what they look like. Historically missing from many other brands, inclusivity helps Siriano prosper, and has also led to culturally relevant, statement-making outfits that are as iconic to us as they are to the designer himself.

In 2016, country star Kacey Musgraves walked the red carpet at the Country Music Association Awards in a lavender number that had Christian Siriano all over it. From the dramatic tiered silhouette to the contrast of the black belt, the look was as whimsical as it was edgy. Fashion gurus praised the dress at the time, with She Knows declaring that Musgraves "owned the red carpet" that night. A decade later, we still haven't moved on, not just from the gown itself but also from the way Musgraves leaned into the drama with a sleek updo and bold, vampy lip. 

Blue Ivy Carter is quickly graduating from mini Beyoncé to her own style superstar. For one, she killed the red carpet at the December 2024 premiere of "Mufasa: The Lion King," where she stunned in a metallic gilded ballgown, complete with a classic corset bodice and full skirt. "This was one of our favorite dresses ever!!" Christian Siriano posted on Instagram in January 2026, in honor of the budding star's birthday. Fans agreed in the comments, especially those who hadn't realized this was a Siriano design. As one wrote, "Ohhhhhh so you were the face behind the dress!!!!!!"

Christian Siriano has dressed Lizzo on multiple occasions, and all of the pair's outfits have been gorgeous. But if one look truly stands out, it's the one-shoulder mini she wore to the Billboard Music Awards in October 2020. The presidential election was a month away, and Siriano wanted to remind the public of their voting power. (Several other stars got on board with the political print, too, from Julianne Moore to Julia Roberts.) Ultimately, Lizzo may have helped to shape history with this frock, so it's unsurprising that Elle billed it as one of the "Juice" singer's most iconic. 

It was one of Halle Berry's best looks ever, and it seems Christian Siriano also has it pinned as one of his all-time best. Half dress of shining armor, half hall of mirrors, this gown won the "Catwoman" star the red carpet at the 2025 Oscars. "This Oscars moment will be one to remember forever!" Siriano wrote on Instagram, along with the very appropriate hashtag #sundayglamour. The standout frock has been posted to his social media a few times, so it's undoubtedly one for the Siriano hall of fame. Plus, aesthetically, it was one of Halle Berry's best style moments in her 50s (if not her whole life).

This carpet might have been more of a brown color than red, but the Humane Society of the United States (now known as Humane World for Animals) benefit that Zendaya attended in 2016 set the scene for one of Christian Siriano's favorite looks. The "Odyssey" star went for monochrome pink, donning a vibrant shirt, pants, and blazer set that looked immaculate on her. "It was one of the first times she wore a really cool suit, something that was like masculine/feminine," Siriano recalled on "Watch What Happens Live" (via WWD). Talk about underrated Zendaya outfits that deserve more recognition!

Christian Siriano has been called upon for many a Met Gala, otherwise known as the fashion event of the year, but fans still can't get over the high-low dress he made for "Forbidden Fruits" star Lili Reinhart in 2021. "My fav look of his is for Lili Reinhart at the 2021 Met Gala," one fan shared on Reddit. It's hard not to agree when you know how much thought went into it. In order to meet the "In America: A Lexicon in Fashion" theme, Siriano included the state flower of all 50 states on this fairy-tale frock.

The crimson off-the-shoulder gown that Leslie Jones wore to the "Ghostbusters" premiere in 2016 has gone down in history as one of Christian Siriano's best. The designer himself is said to remember this one fondly, and fans agree that it went the extra mile. As one Redditor gushed, "All of his looks are so well thought out and constructed but for some reason that simple red sheath on Leslie Jones stays with me." Notably, Jones was struggling to line up a designer for the event, and Siriano saved the day a million times over. 

The most iconic red-carpet dresses don't just look good — they make a statement and embed themselves in the public memory. Whether you loved or hated Whoopi Goldberg's molten-steel structural frock at the 2025 Oscars, there's no forgetting this one. In one Reddit thread, fans even did their best detective work to find the liquid satin lamé fabric this Christian Siriano dress was crafted from. "So expensive but I am completely mesmerised by it, it looks like how faerie ballgowns would be," one commented. 

Inspired by Pablo Picasso, Janelle Monaé (who uses she/they pronouns) attended the 2021 Met Gala in what has become one of Christian Siriano's most monumental dresses. The elaborate look came complete with no less than four hats, along with a functional eye on her bust that actually blinked. Another one of the designer's favorites from his own catalog of work, this look had the wow-factor even at the Met Gala, where avant-garde dressing is as common as a yellow cab in New York City. We're guessing Monaé was happy with the final result since they collaborated with Siriano for future Met Gala looks. 

As far as cultural relevance goes, the velvet tuxedo gown worn by Billy Porter to the 2019 Oscars is the absolute cream of the Christian Siriano crop. Making its way onto many best-dressed lists, not just of that night but of all time, the hybrid garment loosened boundaries around gendered fashion and helped to knock down masculine and feminine stereotypes. The designer told "Watch What Happens Live" host Andy Cohen that the risks he took in designing this piece paved the way for Porter — and hopefully other stars — to feel comfortable wearing what they wanted on the red carpet.
