1. To validate whether fashion brands are willing to provide materials, and which environmental information can be delivered from brands, I visited small fashion brands to participate in this system. I can get some off-cut fabrics from small independent fashion brands. They are sustainable fashion brands and have the information of the materials they are using.

2. To validate whether fashion designers can make fashion items by reusing materials and are willing to record-making process to tell their information, I found the individual designer who is willing to redesign fashion products by recycling unused materials. I delivered these brands' unused materials to one designer and ask her to make whatever she can redesign. Then she made the simple mask and provided making process photos.

3. To validate whether they feel transparent when they reach the environmental information and be willing to purchase redesigned fashion items, I did a prototype with consumers, making them explore Replenish website by using Figma and ask that they realised the sustainable system and feel transparent.
