A clothes designer is branching out by creating an entire range of eco-underwear - made from wood.
Although the knickers and bras are derived from white pine trees there is no risk of the wearer getting splinters in uncomfortable places as they are as soft as silk.
Fibres are extracted from the tree branches before being spun into a fabric which is then used to make the eco-underwear.
Eco-friendly and non-toxic dyes are used to colour the underwear
The makers claim fabric has dozens more microscopic holes than polyester, meaning more air can circulate making them more hygienic. And their natural fibres also absorbs twice as much humidity than cotton which prevents bacteria from growing.
Eco-friendly and non-toxic dyes are used to colour the items in a wide range of shades before they are ready for sale.
All the underwear is packaged in left-over fabric and recycled clothing.
The lingerie has been created by French fashion designer Sophie Young after her child suffered an allergic reaction to dye in clothing.
The production process starts with large branches being selected from white pine trees in North America and Canada during normal harvesting.
The wood is then shipped to Montilliers in France where scientists break it down with the use of enzymes to turn it into a doughy consistency.
