standard US Open leotard kit - but she has ditched the chance to add the flowing pleated skirt like most of her fellow stars.
The German brand produced a gorgeous figure-hugging royal blue number - with Wozza accompanying it with a black jacket that can transform into a bag.
Wozniacki opted to complete the look with her jewellery including a Rolex watch, a Cartier bracelet and gold and diamond necklaces with her kids' names Olivia and James on.
The glamorous and popular tennis star is delighted with the look - and appreciates it is very 'out there'.
Wozniacki said: "I mean, it's the US Open. Why not?
"I think that's my motto at the moment.
"At this point we may as well make a statement. I think that's where I'm at.
"Because I didn't let many people know for a long time, it was kind of a last-minute, ‘All right, let's go for it, let's try this one.'
"I think it's cool. Yeah, this outfit was a last-minute thing from adidas. I think it’s really nice."
And the look has certainly gone down a storm with her adoring fans - although some cheekily compared it to a wet suit, wrestling outfit or cycling lycra.
One said: "we love what Wozniacki is wearing out there."
Another wrote: "I just need to say Wozniacki’s outfit is so good."
And a third added: "Caroline Wozniacki coming back to tennis, having had two babies, wearing this bodysuit, and winning against Petra Kvitova. That’s it. That’s the tweet."
