G Sophie Marceau cannes 2005Sophie Marceau realising her boob had just fallen outOh yikes, it's always a bit of a risk to wear a slinky dress - especially one that has a slink tendency around the boob area.

And now former Bond Girl, Sophie Marceau, is the latest lady to reveal more than she intended on the red carpet at the Cannes Film Festival.

Quite frankly, it shouldn't happen... if a dress doesn't fit properly, then don't buy it or accept the loan of it.

If this is beyond the league of possibilities, then make use of those everyday products to ensure it DOES fit properly through the use of force.

Sellotape, blue-tac, safety pins, paper clips, needle and thread, superglue... the list of products to ensure your dress doesn't slip off and reveal your bosom is endless.

Instead, Sophie chose to ignore all these and stroll down the red carpet just hoping for the best...

She was out of luck, her glitzy gown slipped off her shoulder and revealed her left breasticle for all to see (sans bra).

Sure, she was quick to pop the boob back where it belonged, but not quick enough for the photographers.

Lesson learnt.
