 Just as fashion from 1960 differs from that of 1970 and 1980, so  clothing changed in early America. Wardrobe staff papered their  workspace walls with research diagrams showing the changes in  clothing style from the 1790s to the 1800s to the 1820s:  waistcoat, collar, bustle, wig, hat, and hemline sizes adjusting  over the years. Some costume props would be rejected on authenticity  grounds: "no no no wrong year."
