Tennis star wows crowd with jellyfish outfit

Sports stars are often known for making a big entrance - but how about this for a so-fish-ticated arrival.

Tennis star Naomi Osaka turned up to her first-round match at the Australian Open wearing a jellyfish-inspired outfit.

The Japanese player walked onto court wearing an ocean blue tie-dye tracksuit jacket with ruffled white wide-leg bottoms.

She later revealed that she got the idea to dress up as the marine animal from a book she read to her two-year-old daughter Shai.

Osaka's outfit also featured two white butterflies - one that had been stitched onto her wide-brimmed hat and the other one on her umbrella.

This was a reference to when a real butterfly landed on her face mid-match during same tournament five years ago.

And it seems the unusual choice of clothing brought her a wave of good luck.

Osaka went on to win the match 6-3 3-6 6-4 and progress to the second round.
