I don't believe we have anywhere near the data needed to reliably describe the vocabulary or interests of the people of the 19th century. Most of all history is narrowly focused on the goings on of elites - which may, or may not be broadly representative. I don't think we have quantitative studies or surveys of populations from that time.
Oh, yeah, we basically only have what the elites wrote. Fashion would generally have been an elite thing then, though; it simply wasn't accessible to normal people.
