What was the difference between what ancient Egyptian rich people wore and what encient Egyptian poor people wore

In the old kingdom there was little difference between the clothes worn by the rich and the poor. Men of all classes wore a short kilt made of linen and women wore a long skirt with straps at the shoulders. Rich men and women wore wigs and jewelry while the poor did not. As time went on the clothes of rich people got more elabourate including wearing of silk, while the clothes of the poor remained very much the same.
