Galliffet trousers
Galliffet or gallifet were a style of trousers worn as part of the military uniform of the Soviet Army. They were similar to riding breeches, but adapted to fit in jackboots. Russian dictionaries define "galife" as pants fitting the knees and below, to easily fit the sapogi, and expanding from above the knees.
They were named after French general Gaston Alexandre Auguste, Marquis de Galliffet
