Those who are familiar with the royal family know that Queen Elizabeth II is rarely spotted without her handbag. The accessory, which the monarch has used for years, is not only a staple in her wardrobe but also a useful way to gauge how she feels about particular interactions.

According to Express, the way in which the Queen handles her purse can tell you quite a bit about how she is privately feeling.

If she sets it down on the table or switches it from arm to arm it is said to be an indication to her staff. If Her Majesty rests the strap in the crook of her right arm instead of her left where she usually keeps it that is thought to be an alert to her aides that she would like to wrap up the conversation.

In contrast, if the bag is placed on a table, that is believed to illustrate that she wants the interaction to end within the next five minutes. Additionally, Reader's Digest reports that setting it on the floor is said to mean the same thing, that she would like to swiftly exit the conversation and "be saved from an uncomfortable encounter ASAP."

This is not the first time that Queen Elizabeth has intentionally used her fashion choices to convey an important message to onlookers. According to Robert Hardman, the Queen's biographer, she once said that she wears bright colors so that she can easily be spotted in large crowds.

"I can never wear beige because nobody will know who I am," Hardman recalled her saying when elaborating on her decision-making process.

As for her purse, it seems as though it will retain its relevance and continue to make appearances with her in the future, even during occasions where she meets important people.
