With some of the world's most beautiful women present at this year's Cannes Film Festival, the pressure is on to stand out.

So it was a case of competing for attention last night as Irina Shayk and Tamara Ecclestone both arrived at the De Grisogono party wearing very daring, plunging dresses.

While Irina opted for a sexy silver gown with a thigh-high split and train, Tamara went for a low-cut Grecian-style white dress with cut out panels on the side.

Earlier in the day, Tamara had told her followers on Twitter that she was suffering from something of a dilemma as to what to wear.

She had written on Twitter: 'Really looking forward to the De Grisogono party tonight major wardrobe dilemma though!'

But it seems she managed to decide on an outfit in the end, tweeting later: 'Outfit for De Grisogno party tonight white long Herve Leger dress and Louboutins.'

Meanwhile, Irina appeared to be more than confident with her outfit choice as she posed up for photographers at the star-studded event.

The Russian model, who is dating Cristiano Ronaldo, teamed her stunning dress with a pair of drop earrings, wearing her hair up in a high ponytail to complete the look.

However, while Tamara and Irina both courted attention in their incredible dresses, they had some competition in the glamour stakes from their fellow celebrities.
