What does it mean to be lady-like in the 21st century, and is the term outdated?

I was discussing with a friend after watching an older movie what the definition of "lady-like" was in the past. Certainly this time is more modern and relaxed than times in the past. Is that even a term that people use anymore, and if so what does it mean to be "lady-like" in these times?
