hachiyoku asked: This might seem as a silly question but: What did the women wear under their dresses in russian in the early 1900-1920's ( petticoats, bustles or crinolines... Or something 4th? )

The undergarments spanning those 20 years changed dramatically throughout the time period. I don’t know about Russian specifically, but I have seen photographs of the royal family at this time period and the ladies wear the typical fashions.

In the 1900s, a woman would have worn an s-curve corset, bust and hip pads (under the corset), and petticoats. In the 1910s, the corset was straightened out (no s-curve, no hip or bust pads) and she wore petticoats, as always. In the 1920s, the fashions changed drastically and a lady had on much less underwear - usually some sort of little bra, a girdle-type structural garment to smooth everything down, and a slip.
