A dress or skirt made out of cotton is the same material as cotton pants.
Today is hot, so I have put on a knee-length denim skirt (made out of the same material as a pair of jeans).
So, there is nothing to be afraid of is there?
I shall still wear my skirt to my job this afternoon.
I have done this several times now, with no reaction at all.
The only fear is inside your own head.
