where to buy lightweight cotton clothing ?

I have an old pair of cheap cotton trousers that I like very much,
they will need replacing by next summer [male]
They have a stretchy waistband and are made from a very lightweight breathable cotton - very nice in hot humid weather.
They are quite exotic with multicoloured thin vertical stripes, this style probably has a name but I don't know it, no labels inside.

I'm also looking for extemely thin lightweight cotton one coloured t-shirts with no logos. more pink or yellow than black or grey preferred
Any uk sources appreciated !

thanks, Aviator

 

It wouldn't be that hard to make some. Pants are very easy.... Check out thrift stores, too.

 

For the t-shirts you could try a craft superstore like AC Moore, Michael's, or Ben Franklin. They usually have them on sale really cheap and they have light colors.
Hope this helps
