​To participate in our Earth Day Sustainable Pop Up Marketplace, brands and resellers must meet the following sustainability criteria:

1. Business Ethics & Transparency

• Must have a clear sustainability mission statement aligned with ethical production, circularity, or resale.

• Provide transparent information about sourcing, materials, and business practices.

• No greenwashing—claims should be backed by certifications or verified practices.

2. Smart Material Choices (For New Brands Only)

• At least 80% of products must be made from:

  • Certified sustainable fabrics (e.g., GOTS, OEKO-TEX, FSC-certified materials).

  • Recycled or deadstock fabrics.

  • Natural fibers with low environmental impact (organic cotton, linen, hemp, Tencel, etc.).

• No use of virgin fur, exotic animal skins, or feathers. (Except vintage ?)

3. Circularity & Waste Reduction

• Brands must minimize waste by using recyclable or reusable packaging.

• Encourage repairs, take-back programs, or end-of-life product solutions if applicable.

4. Resellers & Secondhand Vendors

• Must ensure that at least 80% of inventory is secondhand, vintage, or upcycled.

• No fast fashion reselling unless part of a verified slow fashion resale initiative (e.g., luxury authentication, reworked fast fashion).
