Theory has made progress with their 'Good Theory' initiative and commitment to sustainable materials, but lacks full transparency in their supply chain. While they've improved their use of responsible wool and better cotton, their animal welfare policies need strengthening. The brand shows moderate effort in reducing environmental impact but could improve their factory auditing processes and worker welfare programs. Their parent company Fast Retailing provides some oversight, but Theory could be more forthcoming with specific sustainability metrics and goals.
