Quality Analysis 70/100
This blazer is crafted from a mid-weight cotton-blend, offering a good balance for everyday wear. The inclusion of nylon and elastane suggests some inherent resilience and shape retention, though the "non-stretchy" fabric description might be a misprint given the elastane content.
Comfort Assessment Not Available
This blazer offers a comfortable, slim fit thanks to its cotton-blend fabric with "plenty of stretch" and an unstructured shape with softly sloped shoulders. However, the "non-stretchy fabric" mentioned in the Size & Fit section introduces a contradiction that prevents a definitive comfort assessment.
Sustainability Impact 70/100
This blazer is made from a cotton-blend with nylon and elastane, and the text does not provide any information about recycled content or other sustainable material sourcing.
