bras were a cheaper alternative to corsets. and yes, they were popular and not as oppressive as hollywood would have you believe, and they were considered good for back support. Bras didn’t need nearly as much metal or time. And since they were cheaper, they were more common. At least, from things I’ve heard elsewhere.

are the books fucking or are they about fucking? are pictures included?

It is unfortunately a bad translation. It says “Do not throw away your trash here please.” But I like it.
