A thing I neglected to add to the end of my post on The Silver Dress:
I found myself wondering, as I read The Silver Dress, what “American cloth” might be. And apparently I wasn’t the only one, as you can see from this 1913 inquiry in The New York Times. But these days, we have the internet, so I was able to find an answer here, from an 1892 Complete Dictionary of Dry Goods.
