wo New York-born brands come together for the first time as sister labels with the launch of 525 America x Derek Lam 10 Crosby, a limited-edition collaboration bringing together the distinctive design languages of two brands united by a shared appreciation for New York’s energy, culture and everyday style. Launching for pre-order on September 22nd and orders shipping on October 7th, the collection will be available exclusively at 525america.com and select retail locations to be announced.
The collaboration follows NYC Alliance’s acquisition of Derek Lam 10 Crosby in May 2026, bringing the brand into the same portfolio as 525 America. The partnership represents a natural intersection of the brands’ shared commitment to intentional design, quality craftsmanship and accessible price points.
“Bringing 525 America and Derek Lam 10 Crosby together felt incredibly natural. Both brands were born in New York and share a belief that great design should feel relevant, well-crafted and accessible. This collaboration brings together 525’s knitwear heritage and Derek Lam 10 Crosby’s more structured, modern point of view to create something fresh, while staying true to what makes each brand distinct,” says Wen Huang, Head of Marketing at NYC Alliance.
The 525 America x Derek Lam 10 Crosby collection creates a dialogue between softness and structure, classic and contemporary, ease and intention. 525 America’s heritage in high-quality knitwear is reinterpreted through the more directional lens of Derek Lam 10 Crosby, introducing new proportions, tailored shapes and a distinctly New York sensibility to familiar wardrobe staples.
Cashmere, wool and cotton knits are paired with tailored silhouettes and mixed fabrications, extending that contrast across the collection. The palette spans charcoal, army green, navy and carob brown, with hardware and lace details adding a modern edge. From matching sets and dresses to jackets, suiting and sweaters, the pieces move seamlessly between polished and everyday dressing. For 525 America, the collaboration marks a notable expansion into tailoring, woven fabrications and hardware detailing, while maintaining the approachable versatility and craftsmanship that define the brand.
The collaboration also offers a fresh perspective on the established Derek Lam 10 Crosby aesthetic. Its clean lines and sculptural approach to shape bring a sharper, more directional sensibility to 525 America’s classic knitwear foundation, creating pieces that feel both familiar and unexpected while honoring the distinct identity of each brand. The collection reflects the brands’ shared commitment to considered, fashion-forward design at an accessible price point, without compromising on quality or craftsmanship.
The 525 America x Derek Lam 10 Crosby collaboration will be available for a limited time exclusively at 525america.com,
