Just found these ADORABLE 1930s cotton velvet shorts with contrasting liner (coming to my etsy shop shortly). How do I know they're from the 1930s? A National Recovery Act (NRA) label. This is one of those labels that can help a person pinpoint the era of a garment quite precisely (this tells us these shorts are from 1933-1935). Aren't they *so* much like something worn by a chorus girl in a Busby Berkeley production? I think so!
