Materials (1 point):

First, we check the materials, they should be either organic natural fabrics or recycled/upcycled fabrics.

Sustainability:

Transport (1 point):

Fabrics and products should be conveyed by truck and not plane

Packaging (1 point):

Plastic-free packaging are a must for any sustainable brand. 

Not only materials and transport make-up for the sustainability score. The origin of the materials, the production process and waste, scraps management.

Ethicality:

Humans (1 point):

Good working conditions (hours, salary, day off) seems normal to us, but apparently not to every brand.

Animals (1 point):

Vegan or cruelty free.

Bonus points: 

Other values; after-life service, circular production, body positive, non-photoshopped pictures, zero waste...
