Sarah J. Maas's 'Call Her Daddy' Interview Outfit Confirms One Theory: She's a Fashion Girl

At 8 p.m. ET on March 4, every adult woman with Sarah J. Maas's A Court of Thorns and Roses series on her bookshelf will be glued to Alex Cooper's "Call Her Daddy" podcast. It's in this interview that Maas, according to a teaser, is ready to "just tell you" what's coming next. (Hopefully, the sixth novel in her ACOTAR universe.)

Long before any romantasy readers tuned into the broadcast, the ones who are also tracking Fashion Month happenings—like this senior editor—got confirmation of another long-held theory. Judging by her Guest in Residence sweater, Sarah J. Maas is still very much popular literature's reigning fashion girl.

For her first major interview in nearly two years, Maas is sitting down with an It girl-beloved knitwear brand as the centerpiece of her outfit. Guest in Residence, the label behind her "seaglass" cashmere cardigan, was founded by Gigi Hadid; A-list clients include Taylor Swift, Hailey Bieber, Hailee Steinfeld, and Sabrina Carpenter. The No.1 New York Times best-selling author styled her easy cardigan just like any GiR girl cozying up with a book: She paired it with jeans, gold necklaces, and loose waves. While the style is long-gone on Guest in Residence's direct site, it's still in-stock at Bloomingdale's and FWRD.

Sourcing one of fashion insiders' favorite (and hype-worthy) cashmere brands doesn't come as a surprise for fans who've tracked Sarah J. Maas's previous interview outfits. When she was promoting her last release, 2024's House of Flame and Shadow, she worked closely with stylist Michaela Erlanger on a series of literary designer looks. For a stop by The Kelly Clarkson Show, Maas wore a red Valentino midi dress that coordinated with her latest book cover. A few weeks later, she sat front-row at Tory Burch's New York Fashion Week show in a sleek collarless jacket and handbag from the brand.

Fans with a PhD in the Maas-verse will no doubt find hundreds of details to unpack from the author's "Call Her Daddy" interview and the outfit she selected for it. Is "seaglass" blue a nod to the pastels of the ACOTAR world's Spring Court? Is styling a "cardigan" a hint that Taylor Swift played on Maas's writing soundtrack? Until the interview goes live, no theory is off-limits. From the tags alone, the best-seller's knowledge of IYKYK fashion brands is one hundred percent confirmed.
