• Tennis star donned £50 top and £60 tennis skirt from Nike throughout US Open
• Many fans went wild for her outfit online, comparing her to Wonder Woman 
• Meanwhile the pieces quickly began to sell out in several sizes online  

Fashion fans went wild for Emma Raducanu's tennis kit last night as they compared the teenager's bold red and blue outfit to Wonder Woman.

The 18-year-old, from Kent, achieved one of Britain's greatest sporting victories in Saturday's thrilling final, becoming the country's first female Grand Slam champion in 44 years. 

The tennis sensation, who was sitting her A-levels earlier this year, became the first Brit to win a major since Virginia Wade at Wimbledon in 1977 and is the first qualifier to triumph in a Grand Slam, in either the men's or women's game.  

Throughout the competition, Emma wowed tennis fans with her effortless style, donning a £50 red and navy tennis tank and £60 retro style skirt from Nike for her matches. 

Posting online, many compared the ensemble to Wonder Woman's trademark outfit.

One commented: 'If there were a prize for the most fire outfit, Emma Raducanu would also win that.'

Meanwhile another wrote: 'This Emma Raducanu dresses in Woman Woman colours and is playing like Wonder Woman too! Whatever happens from here, she is amazing.'

A third added: 'Emma Raducanu looks like Woman Woman. GO GIRL! You got this.'  

'Watching the US open finals and I super love Emma Raducanu's outfit', another said.

One commented: 'Okay, Emma Raducanu definitely has the best outfit. Fashion win.'

'Watching tennis for the first time and all I really have to say is that I'd like to purchase Emma Raducanu's entire outfit,' another added.

Shoppers have rushed to get their hands on Emma's trendy red tank top and navy blue skirt during the competition, with the pieces selling out in several sizes on Nike's website.

The £50 top features a ribbed trim and a classic V-neck collar and is described as 'bringing some '80s flavour back to centre court.'

An online description highlights how 'lightly oversized armholes complete the retro look' but also 'give you plenty of room to serve and hit overheads'.

Meanwhile the matching £60 skirt, which is currently sold out in both XS and S sizes online, is also described as being a 'retro throwback.'

According to Nike's website, 'with its subtle sheen and colour-blocked mesh pleats, the flowy design embraces the rebel vibe of '80s tennis.'

Life will never be the same again for the teenager as she claims a £1.8 million cheque - more than her entire career winnings to date - and soars up the rankings from 150 to 23.

Millions back home were watching, including the Queen who sent a letter from Balmoral, writing: 'It is a remarkable achievement at such a young age, and is testament to your hard work and dedication.'

She was joined by the Duke and Duchess of Cambridge who hailed her 'stunning performances and historic Grand Slam victory!'

Boris Johnson said 'we are all hugely proud of you' as he praised Raducanu's 'extraordinary skill, poise and guts.' 

Tennis pundits heralded the victory as not simply an historic triumph for a British player, but as a landmark victory for the sport.

'It's a miracle' said former Wimbledon champion Chris Evert. 'This is a kid no one had ever heard of until a couple of weeks ago. Now she's the biggest name in sport. She's stolen all our hearts.'

After her victory, Raducanu fell to the ground crying tears of joy before kissing her silver trophy and beaming at the adoring 24,000 fans inside the Arthur Ashe. 

The Briton said: 'Thank you to everyone here in New York for making me feel so at home from my first qualifying match all the way through to the finals. Leylah's always going to play great tennis and always going to fight… I knew I had to dig deep.

'I think it shows that the future of women's tennis – and just the depth of the game right now – is so great. I think every single player in the women's draw definitely has a shot of winning at any tournament.

'I hope that the next generation can follow in the steps of some of the greatest legends', she added, naming Billie Jean King, who presented her with the trophy.
