Venus Williams has been showing more off than her tennis skills at this year's Australian Open.
While playing her fourth round match against Italy's Francesco Schiavone, Venus showed off her new on-court outfit. During the rallies her skirt repeatedly lift up showing off her backside.
Fortunately for the millions of people watching at home, she was wearing 'flesh coloured' shorts underneath.
Even though she describes herself as "a really private person", she 'tweeted' to her her 438,000 Twitter followers:
"Yeah, this is completely my design. I kind of just sketched it out. It was a process.
"Over time it was one of my old sketches and kind of got recycled and I kind of sat on it for a while.
"Finally it came out. The whole idea is just about an illusion, and the illusion is that I'm wearing, like a deep V-neck.
"Obviously the most effective part of the illusion are the slits. Then the idea was to wear shorts that were like the same colour as my skin, so it works very well apparently."
Maybe it worked a bit too well as some spectators thought they were seeing more than they would have liked.
Her sister Serena is also competing and has the same taste in clothing, but for the Australian Open she has chosen a more conservative look.
Are outfits getting out of hand?
Should they just go back to Shirts and shorts?
Or are they setting new sporting fashion trends?
