Alexandra Daddario (40) Goes Full Retro Glam in a Little Black Dress for New Photos
Alexandra Daddario has had quite the year, both on screen and on social media. The actress turned 40, went through a split from Andrew Form, and has been gearing up for the return of ‘Mayfair Witches’, all while keeping her 22.5 million Instagram followers entertained with a steady stream of fashion moments.
Black has been a recurring theme in her wardrobe lately. Just a few weeks ago, she posted a draped little black dress paired with a bold red lip and jewelry from Sharra Pagano, and earlier this year she wowed in a backless black Brandon Maxwell gown for the AMC Upfronts.
Now, Daddario has added another dark, dramatic look to her collection. In new photos shared on her profile, the actress shows off a black mini dress with a sweetheart neckline, a structured bodice, and a short flared skirt.
The first image is a close-up selfie that leans fully into old Hollywood glamour. Her dark hair is swept into a voluminous, curled updo with loose tendrils framing her face, and her signature blue eyes take center stage against the floral wallpaper behind her.
The second shot is a full-length mirror selfie that shows off the complete outfit. Daddario finished the look with pale pink pointed-toe heels, a playful contrast to the moody black dress, and posed casually in a cozy, lived-in bedroom.
The post quickly drew attention online, with the photos racking up thousands of likes and hundreds of saves within hours. Fans flooded the replies with compliments, praising the throwback styling and the striking hair.
It’s a familiar reaction for Daddario, whose fashion posts regularly go viral. Her summer vacation photo dump, filled with bikinis, wine, and a chic cutout dress, also earned plenty of buzz just weeks ago.
The new photos arrive right after a big weekend for the actress. On October 9, Daddario hit the Main Stage at New York Comic Con for AMC’s panel, turning heads in a pale pink sequined sleeveless gown with a high neckline.

She was there to promote ‘Anne Rice’s Mayfair Witches: Salem Coven’, the show’s third season. Daddario was joined on the panel by co-stars Harry Hamlin, Tongayi Chirisa, Betsy Brandt and Eliza Scanlen.
The new season moves the story to Salem, Massachusetts. Daddario’s Rowan will face ancient magic and new bloodlines as her own power continues to grow. The season is led by co-showrunners Esta Spalding and Tom Schnauz. ‘Mayfair Witches: Salem Coven’ premieres on December 30 on AMC and AMC+.

Daddario’s fashion choices this year have ranged from a red leather look in February that gave off Carmen Sandiego vibes to her sparkling Comic-Con gown. Through it all, she has proven she can pull off almost any aesthetic.
Her latest post shows a softer, more personal side, blending at-home selfies with full glam hair. With ‘Salem Coven’ on the horizon and a promotional tour likely ahead, fans can expect plenty more striking looks from the star in the coming months.
Whether she’s dressing up for a red carpet or snapping a mirror selfie at home, Daddario clearly knows how to make a little black dress feel fresh. These new photos are the perfect warm-up for what promises to be a busy season.
