Reese Witherspoon and her daughter, Ava were twinning in co-ordinating looks as they enjoyed an al fresco dinner together.

Reese took to instagram on Thursday (3 August) to share the sun-kissed snap of the pair in matching dark shades, as they enjoyed a meal and glass of wine at a prestigious event.

Reese brought daughter Ava Phillippe for conservation organisation Oceana's SeaChange Summer Party, and the pair both wore strapless dresses with ruched detailing. Reese wore a pale green, midi version of the dress while Ava went for a slightly longer look in white.

The pair both wore their long blonde tresses down in soft, beachy waves and Reese shared snaps of them getting ready together in their dressing gowns for the event last month, on her Instagram account at the time.

In the first photograph included in the post, the pair pose for a selfie together, showing off their soft, peachy make-up looks.

In the third and final image, they smile for photographers in their co-ordinating dresses as they arrive at the event, hosted at the Waldorf Astoria Monarch Beach Resort and Club in California.

Reese was attending the summer party with the event's sponsor, Biossance skincare and revealed that she was using the brand's squalane and vitamin C rose oil.
