Princess Diana previously showed off her cleavage while dining out.

In a throwback photo posted by a fan account this week, the Princess of Wales is wearing a black tank top while eating at what looked like a restaurant. Based on the expression on her face, the mom of two looks a bit sad or bored.

Princess Diana also places both of her hands on her face, which suggests that she’s not enjoying herself. But the most standout thing from the throwback photo is the fact that the former royal bore her skin.

It was very rare for the late Princess Diana to show off her cleavage when she was out in public. In fact, she even used a unique tactic to make sure that the paparazzi won’t be able to snap compromising photos of her.

Handbag designer Anya Hindmarch used to help Princess Diana pick out her accessories. While speaking with The Telegraph, Hindmarch called Prince Charles’ ex-wife as a very loyal customer who was also a lot of fun.

Hindmarch said that Princess Diana used to laugh at the fact that they created a so-called cleavage bag for her. The bags were used to cover the royal’s cleavage whenever she steps out of her car.

Town & Country uploaded several photos of Princess Diana stepping out of her private vehicle with one of her hands carrying a small clutch bag. In all of the photos, Princess Diana’s hand is carefully placed over her cleavage especially if she’s wearing a revealing outfit.

As such, a photo of the late Princess of Wales showing off her cleavage while dining out is definitely a rare occurrence.

In another throwback photo, Princess Diana looks stunning in her red sleeveless dress. In the snap, the Princess of Wales has a smirk on her face, her right hand is placed on her right hip, while her left hand is resting on the backrest of a chair.
