What is Thinking MU?

Thinking MU is a Barcelona based sustainable fashion brand that positions itself as a pioneer of conscious, ethical design. Its collections are built around durable, timeless pieces intended to last and to push back against fast fashion overconsumption.

Products and positioning

The brand focuses on materials and processes with a lower environmental footprint:

  • Organic cotton, Tencel and recycled fibres
  • Low chemical materials and plant based dyes
  • Water saving techniques
  • Production with local workshops

Distribution

In Barcelona the brand opened a small "mutant" pop up shop whose layout changes every week. The space was designed by the interior studio PPT Interiorismo, led by Helena Puig, using mobile stainless steel shelving that can be reconfigured. Thinking MU is also carried by independent retailers, including concept stores in the Netherlands.

Why it matters

Thinking MU is one of the Spanish labels that has made sustainable materials and processes a core part of its identity rather than an add on, and its changeable shop format shows a creative approach to small scale physical retail.
