What physical features seperates an Czech women from a Polish women?

Polish girls tend to be more influenced by their slavic descent while Czechs have been mixed more over the centuries. Therefore, you get more of the typical slavic features such as round faces and honey-blond hair in Polish girls. Czech girls are taller (from when the Swedes came through several times during, I believe, 30 Year War) and tend to have more oval as opposed to round faces.
