For me, each day begins and ends with wanting to learn a little more about the secrets of spider silk.
I call upon governments to start supporting companies to use more sustainable materials in their products instead of continuing with antiquated incentives, such as import duties on synthetic materials that are in principle much higher compared with those placed on leather goods regardless of the environmental footprint.
I love linen in soothing colors for any room in the house.
Loose, breathable fabrics are great... choose brands that have soft blazers such as loose linen or cotton - it doesn't have to be a structured blazer with shoulder pads.
Sustainability goes across everything I do with Adidas and everything I do with my own house, so the Olympic kit is no exception. It is incredibly environmental in the way that it is manufactured. For example, there's no leather; it's free from PVC. There's lots of woven materials, which means a lot less waste.
The next time you see a spider web, please, pause and look a little closer. You'll be seeing one of the most high-performance materials known to man.
I think natural fibers look better over time. The more you wear them, they look even better.
I won't wear fur - never, ever. I'm an animal lover. I wouldn't even wear faux fur. I prefer to go the cheap route and not shave my legs.
In most matters regarding apparel, I am a big fan of natural fibers - wool, cotton, and so on. Not when it comes to socks. An elastic fiber of some type is necessary.
Depending on the season, between 20 and 30 percent of my collections contain some sort of eco or sustainable element, whether it's a beautiful organic fabric or a natural dye. And obviously I don't use animal skins or fur of any kind.
I was never a chiffon and satin person. I am always a cotton person. It's just the way I am.
I grew up in the age of polyester. When I got to touch real silk, cotton and velvet, the feel of nonsynthetic fabrics blew me away. I know it's important how clothing looks, but it's equally important how it feels on your skin.
I started to grow microbial cellulose to explore an ecofriendly textile for clothing and accessories but, very quickly, I realized this method had potential for all sorts of other biodegradable consumer products.
To me a lush carpet of pine needles or spongy grass is more welcome than the most luxurious Persian rug.
It's like the spiders are sharing an ancient secret with me, and that's why I'm going to spend the rest of my life studying spider silk.
I prefer 100 per cent cotton Ts. They are kinder to lumps and bumps than figure-hugging stretchy Lycra ones and feel nicer against the skin. Extra-long-sleeved T-shirts are a lifesaver for me. I wear them either underneath a shirt with the sleeve pulled out of the cuff, or underneath gypsy tops, tunic tops and waistcoats.
Everything I do, I try to think, 'Okay, what are the ramifications?' Like, with the clothes I wear, I prefer if it's grown organically, because cotton - which is what's used in most clothing - takes up 50 percent of all pesticide use.
I'm a little bit of a hippie at heart, so I always wear things that are comfortable and flowing.
I love a good wool suit, and I appreciate the fact that it's a natural fiber. I know where it comes from, and I know how it's bred. And it's built to last. It breathes, and it feels good.
Beautiful fabrics last; synthetics don't. Certain fabrics, such as linen or cotton, develop their own character over time.
I started to work with cotton fabrics. I used cotton because it's easy to work with, to wash, to take care of, to wear if it's warm or cold. It's great. That was the start.
Being the son of a handloom weaver, I have knowledge of cotton and some other material.
If we have authentic, honest, earthy materials in our houses, we'll be more authentic, honest and natural.
Industrial hemp is a safe substance with many practical commercial applications.
Pretending that the fashion industry isn't in part based on leather would be quite stupid of me, but at the same time, there is another way of doing things - even outside of leather. I don't use PVC either, for example, because it is harmful.
