1700'S German clothing

Hello everyone, I'm a huge history and fashion nerd and currently I'm doing a book that joins both things and I've been having a huge doubt, how it's the german working class clothes like?

I searched multiple articles who said that it was cotton on the fabrics but due to the AI I don't trust google anymore so I went to ask the old and good human intelligence. Can someone please help? :3 and huge huge thanks for anyone that can answer my doubt ^^
