Well, in my quest to determine our family water footprint I have been looking at the water footprint of cotton products - see the link to the water footprint website.
1 pair of jeans = 10, 850 litres of virtual water
1 t-shirt = 2,7,20 litres of virtual water
(Source http://www.waterfootprint.org/Reports/Report18.pdf )
These are average figures and the water used to produce cotton products varies greatly between countries the range of water used to produce the fabric being between 6 and 21.5 million litres per tonne. However this compares with a virtual water content for tea of between 5 and 16.6 million litres per tonne and coffee of between 6 and 49 million litres per tonne depending on where the crop is grown.

In the UK we buy around 86 million pairs of jeans per year - that's around 372, 000 (yes thousand!!) olympic size swimming pools of water per year!
So after this poultrydiscussion we will definitely be looking at our clothes in a different light!
