Running from December 8-10, the fair will display modern and contemporary art from 277 galleries.
Serena looked to be in great spirits as she posed with friends once inside the event as she enjoyed the VIP preview day.
Meanwhile her sister Venus posed up a storm later in the day as she turned heads at the Art Basel Miami Beach dinner at Cote Miami.
The tennis star, 43, put on a very leggy display as she donned a sparkly little black mini dress patterned with a silver sequined moon and constellation pattern.
She showed off her ample cleavage in the square necked gown, while she styled her brunette locks straight over her shoulder.
Venus completed the look with some black heels while she posed confidently with her hand on her hip.
It comes after Serena claimed her breast milk helped heal her sunburn.
The mother, who gave birth to her second daughter in August, recently took to TikTok to detail her unusual hack.

She dabbed the breast milk on her undereye, which had been left scorched by the sun, before revealing that ‘it worked’ to soothe the area.
But it seems that some of her 1.6 million followers were unsure about her unique remedy.
In the clip, which has so far been viewed more than 47,000 times, Serena wears a black crop top and matching pants.
The mother-of-two, who stepped away from the sporting limelight last summer, speaks directly to camera from her home in Los Angeles.
She begins: ‘So I completely got burned under my eye – don’t ask…
‘I have sensitive skin. I was in the sun. Long story. Anyway, I’m trying some breast milk.
‘It works for my kid. They say put breast milk on everything and I have a lot of extra so I’m going to try it for a week or so under my eye and see how it goes.’
