The Victorian Age
The United States during the second half of the 1800s was in a stage called "The Victorian Age." The basic style of this time was actually borrowed from the English or to be more exact Queen Victoria hence the name Victorian Age.
During this period the high class citizens would dress in their finest clothing on an everyday basis. The middle class people would dress as nice as possible but not nearly as showy as the high class. The lower class people would dress in basically rags. Also, during this time sex was not a topic often discussed in the public, usually if you were caught there was a pretty good punishment for that.
The way I see it is that The Victorian Age was a strong time for the U.S., but it's probably a good thing that it's not that way anymore. If it were still that way today there would continuous struggle for the lower class people to get an advantage. When you think about it our society is sort of like that now, but not nearly as radical.
So I would personally like to thank Queen Victoria myself on behalf of all the fine citizens of the U.S. in the late 1800s. Without her the world wouldn't be the great place that we all know and live in. Thank you Victoria.
