Sarah Pidgeon Wore Custom Chanel by Matthieu Blazy at the 78th Emmy Awards

Sarah Pidgeon made her Emmys debut count. The "Love Story: John F. Kennedy Jr. & Carolyn Bessette" star, nominated for her breakout performance as Carolyn Bessette Kennedy, walked the blue carpet at the 78th Primetime Emmy Awards on September 14 in a look that felt both minimal and dripping in detail all at once.

Sarah wore a custom lavender Chanel gown designed by creative director Matthieu Blazy, a floor-length silk slip with a cowl neckline and a long train pooling behind her. What set the dress apart was the jewelry draped directly onto the fabric, layered strands of pearls and crystals cascading from the shoulders down across the bodice, anchored by small gold floral clasps at each strap. A delicate diamond pendant necklace layered on top added even more sparkle without overwhelming the soft, silky base of the gown.

It's no surprise Sarah reached for Chanel again, she's a brand ambassador and has worn Matthieu Blazy's designs repeatedly this year, including a feather-trimmed tunic at the "Love Story" premiere and a pistachio slip dress for a pre-Oscars dinner. She kept her hair down in soft, loose waves parted deeply to one side, and her makeup stayed dewy and natural, letting the dress's texture and jewelry carry the look.

Sarah joined a wave of stars embracing lavender on the blue carpet this year, alongside Florence Pugh, Emilia Clarke, and Jessica Williams, making pastel purple one of the night's clearest color trends. It's a fitting full-circle moment too: Sarah has spent much of this award season channeling Carolyn Bessette Kennedy's understated, minimalist style off-screen, and this bejeweled Chanel gown showed she can also turn up the glamour when the occasion calls for it.
