What is ACOTAR™?

A Court of Thorns and Roses™ (ACOTAR) is a bestselling romantic fantasy book series by author Sarah J. Maas™. Set in the world of Prythian, the series follows humans and faeries through stories of love, power, loyalty, and adventure. With more than 85 million English-language copies of Sarah J. Maas™ books sold worldwide and over two million ACOTAR-related posts on TikTok, the series has become a global phenomenon with a passionate fan community.

Which Courts, characters, or themes inspired the collection?

The limited-edition ACOTAR™ x Knix collection brings the Courts, characters, and defining moments of A Court of Thorns and Roses™ to life through original silhouettes and exclusive prints across lingerie, sleepwear, and Knix’s signature leakproof underwear.

The collection introduces five new silhouettes inspired by characters and unforgettable moments from the series:

The Nesta™ Silver Flames Corset, inspired by Nesta’s unyielding strength and fire
The Court of Nightmares Lace Teddy & Sheer Skirt, designed to layer together, recreating Feyre's unforgettable turn in the Court of Nightmares
The Starfall Slip & Robe brings Feyre's Starfall night to life
The Elain Lace Thong Bodysuit & Sheer Skirt, which captures Elain’s quiet power
The Amren™ Satin Slip & The Morrigan™ Satin and Lace Slip, signature pieces inspired by Amren's and Morrigan's distinct personas

Why did Knix decide to do a collaboration with this book series?

The partnership marks Knix’s first book-inspired collection and was born from a shared fandom across its team and community. More than 40 ACOTAR™ fans within Knix helped shape the collection, while the brand’s social community overwhelmingly named ACOTAR™ as its most-wanted collaboration. The result is a collection created by fans, for fans, with every detail grounded in the books.

How were the Court-inspired prints designed?

Every exclusive print in the collection began as original artwork created in collaboration with an ACOTAR-obsessed artist on our Knix design team.

Long before these designs appeared on satin, lingerie, or leakproof underwear, they existed in the artist’s workspace—drawn, developed and refined by hand, with details coming directly from the world of the books.

Was AI used to create this collection?

No, AI was not used to design the ACOTAR™ x Knix collection.

We spent over 18 months designing this collection, and there isn’t just one person or team behind the designs.

There are artists who put pencil to paper. Designers who turned ideas into pieces you could actually wear. Teams who worked through samples and details. Artists who painted the sets. And dozens of ACOTAR fans at Knix who brought their own knowledge of the books into the room.

That’s what “made for fans, by fans” means to us.

Not just that we love the books. That fans had a hand in making the thing itself.
