For fellow admirers of cult-favorite brands Cou Cou Intimates—the London-based label renowned for its thoughtfully designed cotton essentials and precious, feminine details—and Sandy Liang, the NYC designer beloved for her youthful, nostalgic sensibility, this is dream news. And, thankfully, we don’t have to wait to get our hands on it. The collection is available to shop as we speak.The partnership marks Cou Cou Intimates’ first-ever brand collaboration, and it’s hard to imagine a more natural fit. True to the label’s signature, the collection centers on organic French poplin trimmed with French lace, reimagined across a range of everyday essentials with whimsical, nostalgia-infused details that feel unmistakably Sandy Liang—including bows, playful prints, and all the girly touches you could want.Photography by Annemarie KuusAccording to a press release shared with ELLE, the collaboration was conceived around a shared philosophy: “You can do anything in a dress and comfy undies.” Presented as “A Guide to Being Well Read,” the campaign encourages curiosity, experience, and thoughtful engagement with the world around us, all while “living out each day with a sense of childlike wonder and humor, embracing the magic within us.”Photography by Annemarie KuusAnd I can confirm: The new pieces fully embody that philosophy. The lineup includes two sweet tank tops finished with miniature bows—a charming design detail beloved by both brands—along with a long-sleeve pajama shirt and matching pants in the collaboration’s exclusive “Sweet Dreams” print. The pink-and-white pattern features scattered sketches of teacups, butterflies, bows, paw prints, and other delightful, Sandy Liang-coded motifs.Rounding out the collection is an equally charming assortment of intimates: briefs for every day of the week, rendered in alternating shades of pink, white, and blue and finished with coordinating embroidery.Photography by Annemarie KuusGiven the devoted followings of both brands, there’s no telling how long sizes will stay in stock. So if something catches your eye, don’t wait to add it to cart.Shop the Full CollectionCou Cou x Sandy Liang The Baby Tank SetCredit: Cou Cou x Sandy LiangCou Cou x Sandy Liang Days of the Week Pants, 7-PackCredit: Cou Cou x Sandy LiangCou Cou x Sandy Liang Pajama ShirtCredit: Cou Cou x Sandy LiangCou Cou x Sandy Liang Pajama PantCredit: Cou Cou x Sandy LiangCou Cou x Sandy Liang The BoxetteCredit: Cou Cou x Sandy LiangWhy Trust ELLEEvery product featured on ELLE.com is independently researched, tested, or editor-approved.
