Husband approved
My husband is a creature of habit so notably switching up his boxers was something I was hesitant about. I’m so glad I did because all he wants to wear now is mntd and just asked for more. Highly recommend.

Your ACOTAR™ x Knix questions, answered.

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.
