Serena, her husband, Alexis Ohanian, and their four-year-old daughter, Olympia, all arrived at what will likely be the champion's last tennis match after announcing her retirement earlier this year.

Olympia was seen rocking white beads in her hair, which fans quickly noticed was a nod to her mom.

Serena famously wore a similar hairstyle when she won the 1999 U.S. Open. Olympia's hairstyle was a sweet gesture to show support to her mom, proving once again that she is Serena's biggest fan.

For fans, it was clear Olympia is her mom's biggest fan.

Besides Olympia's tribute to her mom through her outfit, the little girl was also seen in the stands enthusiastically cheering her mom on.

People also noticed how Olympia's dress matched her mom's.

In an Instagram post, Serena revealed how she worked with Nike to design her black, tutu skirt inspired by the night sky above the court where she will play her last career tournament.

It's safe to say fans were loving the supportive energy coming from Olympia.

The sweet moments between the mother and daughter added an extra emotional layer to the tennis tournament.

This isn't the first time Serena and Olympia have coordinated their outfits.

In fact, the mother-daughter duo frequently match their outfits and share the results on Serena's Instagram. Many of their ensembles are designed by Serena herself who often collaborates with Nike and launched her own S By Serena fashion line.
