How do you walk into a room? Do you slow down your gait and make a gentle approach? Do you bust through the doors with vigor and glee? Whatever your technique, we can all stand to learn from Queen Elizabeth's graceful lead.

Or more accurately, what Lilibet picked up from the Queen Mother. As Town and Country reports, a new documentary Elizabeth: Our Queen (unfortunately, it's only airing across the pond), gives us wonderful intel on how the Queen always makes a great first impression, or more specifically how she enters a room.

"I think the Queen probably when she was young felt walking into a room full of people was rather daunting. So [the Queen Mother] said to her, 'What you want to do, when you walk into a room, is walk through the middle of the door,'" Lady Penn, who served Elizabeth's mother as a lady-in-waiting, also known as a "court lady" (someone who attends a queen or princess), said in the documentary.

"And I think by that she meant, don't sort of go in apologetically. You walk through as if 'I'm in charge.' I think that was very good advice," continued Penn.

We may not be monarchs, but the practical advice is a welcome reminder to be confident and poised when we enter a room—even if we're swapping walking into Buckingham Palace for walking into the in-laws'.
