Serena-tard debuts at Australian Open, makes sure baby's first doll 'Qai Qai' is black

Serena Williams unveiled her latest fashion statement at the Australian Open on Tuesday, and helpfully ended any confusion about what to call the striking garment.

“It’s a Serena-tard,” Williams told reporters when quizzed about her latest look. Made of jade-green lycra with a black-and-white waistband, the skin-tight outfit looks like a pair of disco-era hotpants  attached to a builder's singlet.

In the meantime, Williams says she made sure the first doll her daughter Alexis Olympia received was black, and her second one will be white as she teaches a message of “love for each other”.

The tennis great, in Melbourne in her bid to win a 24th Grand Slam title, is married to Reddit co-founder Alexis Ohanian with their first child born in late 2017.

Williams, 37, said she rarely came across black dolls when she was growing up and wanted to make sure her baby had one.

“Qai Qai is a doll I got for her. I wanted her to have a black doll,” she said after easing into the tournament second round Tuesday.
