As for "traditional German clothing", well, a lot of it that we are familiar with is traditional only back to the 19th century, when things actually became MORE "Germanic"... There's not necessarily a direct line to the 18th century in traditional German clothing. I've not seen deer antler buttons on anything German (or any other nationality) from the 18th century (nor from the 19th century, actually, but that's not my thing). I just don't see the rough antler button thing being done in the 18th century anywhere. I know, I know, it's all rustic and romantic and backwoodsy and stuff, but still... they're just not there. What is there are the same types of buttons in Europe and the East coast. Brass buttons, pewter buttons, silver buttons, bone buttons, fabric covered buttons, Deaths Head buttons, thread buttons, Dorset buttons, etc.
Hooks and eyes were very common in the 18th century among all English and Europeans, and yes, they were (and are) more common to Germans, particularly of the more pietistic and "plain" sects. I'm having a coat made for me right now that I will put hooks and eyes on, befitting my rather pietistic persona.
Again, in the 18th century, buttons were everywhere. They were all the rage. Buttons all over everything, whether it needed them or not. The Mennonites/Amish and others saw it as extravagance, and they eschewed buttons as much as possible (still do). They were also seen as militaristic, as military uniforms were absolutely festooned with buttons. (same with mustaches, by the way... German soldiers were generally required to wear mustaches, so the Mennonites/Amish don't.)
Personally, I detest buttons and want none unless they are ABSOLUTELY NECESSARY, like shirt collars, cuffs, and breeches. I especially hate them on coats. The buttons hang on EVERYTHING. Another reason I'm doing my coat with hooks and eyes! :haha:
Yes, ties were also commonly used, I've seen many period images of shirt collars with a little tie through matching "buttonholes" on the collar instead of buttons or linked buttons. Rifle Shirts were sometimes tied closed on the front with little strips of woven tape. One existing rifle shirt, probably 1790's, has remnants of 4 ties, and I have read accounts of using ties on the front.
Ladies clothes were often PINNED closed!!! How inconvenient that must be! Ouch!
And buttonholes are not really hard to do, but they do take practice, and are no problem at all for an accomplished seamstress or tailor. Remember, people at the time did NOT make everything themselves!!!!!
One thing I just can't get over, however, is the idea of someone being "too poor to afford buttons". They were imported by the barrel full, tons and tons of buttons of all kinds. Even on the frontier, they were not hard to get. And the linked sleeve/collar buttons were also COMMON, even out here in the sticks. There really was no pressing reason to make buttons, especially antler buttons. :idunno:
