A United Kingdom-based company called Superlative Luxury has created an eco-friendly t-shirt priced at $400,000. The t-shirt is made of 100% organic cotton and the manufacturing process uses only renewable energy, such as wind and solar, reducing the carbon footprint by 90%. The t-shirt features a spherical pattern created from 16 one-carat diamonds; half of which are white diamonds and the other half are enhanced rare black diamonds. Due to the company’s preference for greener manufacturing, it takes them four weeks to make a shirt. The t-shirts come with a one-year warranty.
