La Ligne, known for its modern take on stripes and wardrobe essentials, has partnered with Observed by Us, the design line founded by actress Kirsten Dunst and artist Jessica Hershko, on a limited-edition collaboration.

The capsule launches Tuesday and is a playful and nostalgic take on sleepwear, fusing La Ligne’s signature silhouettes with Observed by Us’s hand-drawn, storybook-style illustrations.

The capsule includes 10 pieces of elevated loungewear that features delicate piping, soft cottons, silk and cashmere, patterned in prints drawn from the Observed by Us universe. The line is designed to be worn to bed, around the house, or styled for day.

The offering includes the Women’s Printed Bonne Nuit pajamas ($395) in classic navy and white or a colorful white multiprint, as well as an elevated set in burgundy silk with delicate gold embroidery ($495). Matching sets for children include the Enfant Bonne Nuit pajamas ($125), which comes in white/multi and navy/multi, while a coordinating men’s version of the Printed Nuit pajamas ($395) rounds out the offering.

Accessories include the burgundy embroidered cashmere night mask ($75), matching embroidered slippers ($45), and Mini Marin socks ($55) both in white and burgundy/gold.

“Kirsten and Jessica have created such a whimsical, joyful world — one that we instantly wanted to live in. It’s a breath of fresh air to step into their dreamscape, and we feel lucky to do that through this capsule. Sleepwear felt like the natural way to wander in,” said Molly Howard, chief executive officer of La Ligne, who cofounded the company along with Valerie Macauley and Meredith Melling.

“La Ligne is a brand that we both gravitate towards and have in our personal wardrobe collections. Their simple yet elevated styles and colors align with our sensibilities, and being able to infuse their sleepwear with our out-of-the-box illustrations felt completely natural. Working with Meredith, Molly and Valerie was so much fun and effortless, and we can’t wait to share this collaboration with everyone,” said Dunst and Herschko in a statement.

Observed by Us is a collaborative venture born out of Dunst and Herschko’s shared love for storytelling and illustration.

The La Ligne x Observed by Us capsule will be available exclusively at laligneny.com and in select La Ligne stores starting Tuesday.
