Today's Russian population wears popular western fashion, and like any country/economy, the people dress in the manner they can afford. Today's Russian enjoys jeans and t-shirts, jackets and clothes similar to what is worn in the US. Clothing in the turn of the 18th century in Russia conprised of a shirt, "sarafan", belt and apron. The "sarafan" was a part of peasant womenfolk and urban women. An older garment was the "poneva" skirt.

Well silly, most Russians wear clothes. They are just like Americans in terms of fashion. But they do have one difference. It gets much colder there, so they tend to wear heavier clothes and warm coats.
