Streetwear brand Nerdy has officially rebranded as NDY — short for Not Defined Yet — marking a fresh start with the launch of its 2025 fall/winter collection.
The brand announced the name change and unveiled the new lineup Tuesday on its official online store.
Since its launch in 2017, Nerdy has stood out for its vibrant and bold color palette and distinctive designs that embody a casual yet sporty streetwear aesthetic.
The brand said the new name reflects its ambition to expand its identity, to keep pace with fast-changing fashion trends and further broaden its customer base.
“NDY will continue to pursue designs that go beyond Nerdy’s free-spirited and statement-making styling, taking a step further to focus on fashion that embraces liberated transformation,” the company said. “We look forward to consumers’ interest and excitement for NDY’s new journey.”
NDY also has a new tagline: “Define Nothing. Be Everything.” It represents the brand’s philosophy of breaking molds to create endless new possibilities and embracing evolution. While Nerdy championed individuality, emphasizing freedom in one’s own way, NDY expands this commitment to highlight the freedom to constantly adapt and transform without being confined.
Under NDY, the brand unveiled its 2025 fall/winter collection. Building on Nerdy’s signature track suits, the new designs incorporate NDY’s new logo with richer colors and materials, reflecting the spirit of undefined freedom.
The brand’s flagship piece, Classic NY Track, has now released four additional colors, including navy and pink. It is also available in corduroy fabric, broadening consumer choices. The popular Ribbon Track, which gained traction among consumers last year, has returned with three new colors and velour fabric designs.
The 25 F/W lookbook further emphasizes NDY’s new identity by showcasing diverse and unexpected styling. Under the theme “Your rules. Your style,” track suits are paired with formal shirts or lace-design casual pieces, demonstrating that the clothing line extends beyond training wear to become versatile fashion statements.
