The iHeartRadio Music Awards 2026 red carpet was an all‑out fashion war—and the winners were everyone lucky enough to witness the jaw‑dropping parade of celebrity style. From Taylor Swift’s showgirl‑worthy crystal corset to Sabrina Carpenter’s vintage Versace slip that had fans comparing her to a modern‑day Marilyn Monroe, the looks were nothing short of iconic. But the night’s biggest fashion moment came when Chappell Roan stepped out in a custom chain‑mail gown that weighed nearly 40 pounds, prompting gasps from the crowd and instant meme‑ification across social media. Insiders say stylists have been working around the clock for weeks, with some celebrities reportedly spending upwards of $100,000 on their ensembles. “This was the year everyone brought their A‑game,” a fashion insider told us. “No one wanted to be the one who blended in.” Meanwhile, behind the scenes, drama brewed as several stars reportedly had last‑minute wardrobe malfunctions—including one A‑list singer who had to be sewn into her dress minutes before hitting the carpet. From daring cutouts to show‑stopping trains, the 2026 iHeartRadio red carpet delivered a masterclass in how to command a room before you’ve even stepped inside. Check out every show‑stopping look inside—and prepare to be stunned.
