BAYFLOW and Yurie Chiku Ignite Daily Fashion with New Collaboration
A Fresh Collection of Denim, Knits, and Sweats Designed to Infuse “Excitement” into Everyday Styling
BAYFLOW, the renowned lifestyle brand from Adastria Co., Ltd., is set to launch an eagerly anticipated collaboration with popular influencer Yurie Chiku. Known for her sophisticated casual style and strong following among women, Chiku has co-created three distinctive items: a pair of figure-flattering denim, a vibrantly embroidered knit, and a versatile, perfectly proportioned sweat. These exclusive pieces will be available starting December 10, 2025, at BAYFLOW stores nationwide and through the official “and st” web store. A dedicated web page, styled by Yurie Chiku herself, will also go live on the same day, showcasing the collection’s full potential.
The collaboration embodies a philosophy of making daily dressing an exciting experience, balancing simplicity with playful details. Yurie Chiku’s personal touch is evident in every design, from silhouette to color accents.
“When I received the offer for this collaboration, the first thing I felt was ‘excitement’,” shared Yurie Chiku. “I personally love colors, mixing and matching, and layering clothes and accessories, but I also appreciate simplicity. As I’ve gotten older, I’ve wanted to streamline things. I want to do a lot, but I also want it to be easy. My hope was that planning daily outfits could become an exciting time, rather than a troublesome one, and I believe we’ve achieved that with this project. I’d be thrilled if these collaboration items could become a source of excitement in everyone’s daily lives!”
The Exclusive Collaboration Lineup
1. Yurie Chiku Collaboration Slim Straight Denim
This denim is designed to be a year-round staple, with a strong focus on a style-enhancing silhouette. While wide and loose bottoms paired with compact tops were popular in spring and summer, this denim offers a sleek option to balance voluminous autumn and winter knits, sweats, and outerwear.
It features a longer inseam to accommodate taller individuals, ensuring a stylish fit without compromising length. For those who are petite, a subtle message print hidden on the inner cuff appears when rolled up, eliminating the need for alterations and adding a charming detail.

2. Yurie Chiku Collaboration Hand Stitch Knit
A colorful knit can uplift spirits during colder seasons, but often limits styling options. To address this, the Hand Stitch Knit comes in versatile basic colors—off-white and navy—enhanced with vibrant, colorful embroidery. This design makes the knit an impactful standalone piece, perfect for those who prefer minimal accessories or struggle with coordinating them. It invites wearers to experiment with color combinations, much like using a personal color palette.

3. Yurie Chiku Collaboration Hand Stitch Sweat
This simple yet versatile sweat is crafted to be a complete outfit on its own. Its balanced sleeve volume, rib length, and unadjusted overall length make it easy to coordinate with various pieces. Subtle design elements include contrasting stitching around the neckline and slits at the hem, allowing for effortless layering with innerwear to create diverse looks.

The Future of Kawaii Fashion: A Global Palette
This collaboration between BAYFLOW and Yurie Chiku exemplifies how Japanese fashion continues to evolve, blending casual comfort with thoughtful design. The emphasis on versatility, personalized details like the hidden message in the denim, and the “color palette” approach to knitwear reflects a growing desire for fashion that is both expressive and effortlessly integrated into daily life. Such initiatives, spearheaded by influential figures, are likely to inspire a broader appreciation for accessible, joy-infused fashion, further weaving the spirit of “Kawaii” – not just as cute, but as charming and delightful – into the global fashion narrative.
