Famous for her sartorial elegance, it seemed Paul McCartney's fashion designer daughter, this time forgot to take notice of her own outfit, as she left home to attend a public function.

As she stepped out at an art and design auction, the 35-year-old glamour queen, who is eight months pregnant, sported a see-through outfit that highlighted her bulging stomach to maximum effect.

A sheer black top made of translucent, chiffon, worn over leggings, showed off her heavily rounded tummy, reports The Daily Mail.

Stella McCartney is expecting her second child. She already has a 19-month old son, Miller with her husband of three years.
