Anastasia exposes control underwear in Stella McCartney's polka dot dress

Wardrobe mishap: Anastasia looked stunning at the Pink Ribbon Ball held at London's Dorchester Hotel tonight, despite exposing her control underwear in the classic Stella McCartney dress

It was a worthy wardrobe choice, but Anastasia suffered a slight mishap when she donned her polka dot Stella McCartney dress for the Pink Ribbon Ball tonight.
The 43-year-old looked radiant as she arrived for the event held at the Dorchester Hotel in London, however there was one element of her ensemble which she appeared to have overlooked.
The Left Outside Alone singer's control underwear was visible through the transparent panels of the classic piece.

Thankfully Anastasia looked stunning despite the unfortunate gaffe, completing her look with smoked-out eyes and black patent heels.
Elen Rivas, Hayley Tamaddon, Amanda Lamb, Loose Women's Andrea McLean and Bernie Nolan were also in attendance, with black appearing to be the colour of choice outfit-wise.
Anastasia is a breast cancer survivor, so the event was naturally close to her heart.

The singer discovered a lump during a routine mammogram in preparation for a breast reduction in January 2003.

She successfully completed surgery and radio therapy, and subsequently developed the Anastasia Fund to promote breast cancer awareness among young women.
In 2005 Anastasia was lauded for her international success, having sold over 20 million albums worldwide.

The McCartney dress, which comes in a variety of styles is a celebrity favourite due t its flattering shape.
It has been championed by stars such as Kate Winslet, Liv Tyler and Natalia Vodianova.
Kate Winslet chose a daring thigh-baring style for the Mildred Pierce premiere.
