Our Position: The Opposite Thing

Designed in London — Made in Spain — EU Sourced and Produced

Miista upends the exclusionary practices of the fashion industry to show how we’re actually living now. Over the last ten years, we are proud to have built a brand that, through craft, our community, the risks we’ve taken and a sometimes

bizarre willingness to laugh at ourselves, has made an elegant commitment to the alternative. A dedication to the opposite thing.

What does that mean? That we’re happy to sacrifice profit and to subvert problematic fashion trends for women to create a product that has personality in addition to aesthetic value. A product that knows women don’t really shop using the search words ‘pretty’ now. If we were your friend, Miista would be the odd one at school who grew up and got an attitude and a sense of confidence. You know when it’s a Miista.
