Sine & Cosine is the sum of Dutch culture and luxury footwear.
The Amsterdam-based brand was founded in 2021 by two mathematicians with no formal education in fashion. As outsiders, the two—unaware of any rules or standards—developed their process for designing products. Instead of reinventing the wheel, the two built upon existing structures of Dutch heritage attire, as mathematicians would, interweaving their unique insights and ideas.
This approach equals a collection of products that embodies what luxury means to them: creative exploration and expression without compromising practicality or craftsmanship.
