💡 How Technology is Driving Sustainability

Technology has become a major force in sustainable fashion, making processes more efficient, reducing waste, and enabling new materials and design techniques.

Advantages:

• Less material waste
• Custom sizing reduces returns
• Enables innovative designs

Example: Designer Danit Peleg creates stylish, sustainable 3D-printed garments with minimal environmental impact.
