There is always more to be said, but you may be interested in my recent answers:

In the case of some old French clothing there are super widened dresses that extend way past the shoulder of the wearer. Is there a reason for this?

In England 1700s(?) How did the trend of caked face paint, absurdly large dresses and wigs come about?

These discuss changes in skirt shape and hair/wig-style in the Early Modern period, which were occurring on an ongoing basis to create the effect you're describing. I also have this thread on the quick rate of change in women's dress in the later 18th and early 19th centuries:

Why were some women's dresses from the 1800s actually really simple?

And this one on changes in fashion and decorative arts in the 19th century:

We distinguish the differences between the decades of the 1900s (70s, 80s, 90s) very distinctly. What were some specific differences between the decades of the 1800s?

As I argued in this thread on the use of decade terminology, twentieth-century decade stereotypes are, on the other hand, not accurate. The 1910s stereotype is based on the clothing of the early 1910s, with a high waistline and long, narrow skirt; the 1920s stereotype is based on the clothing of about 1925 through 1927, with a dropped or nonexistent waistline and a knee-length skirt. This structure leaves no room for fashions from the late 1910s, which generally feature a raised waistline, a loose silhouette, and a calf-length skirt, or the very long skirts of 1922-24. The decision to take 1912-1914 fashion as emblematic of 1910-1919 is essentially arbitrary, and even deciding that the dividing line for an era should be between the 9 of one decade and the 0 of the next is arbitrary.
