Reese Witherspoon and her look-alike daughter Ava coordinate in strapless dresses for Oceana’s annual SeaChange summer party

Reese Witherspoon and daughter Ava looked more like sisters than mother and daughter as they stepped out Saturday in Southern California.

The recent Oscar winner, 47, showed off her fit figure in an elegant light green strapless dress with ruffles on one side.

Her long blonde hair was styled in loose waves with curtain bangs.

Kotb Media wore natural makeup with a sun-kissed cheek and a natural pink lip.

Ava followed her mom’s stylish lead, wearing a coordinating ensemble featuring a white strapless top and matching wide-leg pants.

The influencer’s long, blonde hair was also styled in loose waves.

She wore natural makeup and added a touch of contrast as she wore a black choker.

“Perfect summer night with my girl @avaphillipe learning all about @oceana’s amazing conservation work,” Rhys wrote next to the photo on social media.

Ava shared some pics of herself and Reese inside the resort to her Instagram Stories, writing, “Lovely evening spent with my favorite mum and @biossance.”

“Celebrating all the amazing work oceana is doing to protect our oceans.”

The pair were among the attendees of the 16th Annual Oceania Summer SeaChange Gala.

The fundraiser was held at the Waldorf Astoria Monarch Beach Resort in Dana Point.

The Ocean Conservancy has been working to protect the oceans from pollution, overfishing and climate change for more than 20 years.

Reese is the global brand ambassador for biosancean Ocean Partner.

As part of its promotional materials, the company said its veganism saves two million sharks annually from overfishing.

While doing well, mother and daughter also had a good time.

They put on their hotel robes and enjoy a little pampering in their room.

Oceana’s special guests for the evening included John Diana Raphael as Master of Ceremonies, and music from the movie Third Eye Blind.
