Isla Fisher and Shawn Johnson look beautiful in the same floaty, strapless gown...

It's not often you see an Olympic athlete and an actress going head-to-head, but nothing's ever ordinary here at Sugarscape HQ, and when we found out that American gold medal winner Shawn Johnson and 'shopaholic' actress Isla Fisher had both worn the same dress, they were thrown into a fashion face-off!

The petite ladies have gone against the rules of fashion and worn matching strapless maxi dresses by Elizabeth and James. But you're bound to prefer one look more than the other...

Isla went with loose waves and armfuls of bangles for a hippy cool look.

Shawn instead paired her dress with dangly earrings and a big smile!

But which of the ladies wore it best? Was Isla's hippy take more your thing, or do you prefer Shawn's modern look?

Comments please!
