What is Summum?

Summum is a Dutch womenswear brand from Amsterdam, founded in 1998 by Jos and Jorien Wijker. The founders describe it as boutique-like and family-run, aiming to be selective rather than exclusive and to avoid becoming a chain.

History

The company started in an old, unheated school building in Amsterdam-Noord, where the founders handled everything themselves, from design to packing and marketing. Mareille Post, the first employee, has designed for the brand ever since. Summum marked its 25th anniversary with a campaign around its long-standing customers.

Products and positioning

Customers describe the clothing as high quality, feminine and creative. The brand stresses creative freedom and a constant flow of new ideas in design.
