The ladies stepped up their fashion game for the Serpentine Gallery summer party at Hyde Park on Tuesday.

With the beautiful warm weather, these A-listers opted for toned-down glam looks for the highlight of London’s summer social calendar.

Here are some of our favorite standout dresses from the event:

1. Alexa Chung in Erdem

Of no relation to Jamie Chung, trendsetter Alexa Chung opted for a strapless Erdem fall 2014 dress, which she paired with flat ankle-strap shoes. While the frock might look like a typical black dress, it gets pretty interesting upon closer inspection.

We really love the lace hem and the stitching details on the bodice. The only thing missing in this look is a pop of some perky-colored accessories.

2. Gemma Arterton in Prabal Gurung

Most monochrome looks are boring, but Gemma Arterton totally pulled off her all-red ensemble. Dressed in a fun two-piece Prabal Gurung Resort 2015 outfit, Gemma showed off her flat tummy and toned legs.

She styled the flouncy look with matching sandals and finished with sexy windswept hair.

3. Samantha Barks in Lanvin

Samantha Barks also rocked a monochrome ensemble, but hers didn’t translate as well as Gemma’s.

Although we really like the metallic pink of this Lanvin Spring 2014 dress, the styling with a ribboned clutch and matching pumps was just too plain. The dress is gorgeous, though.

4. Keira Knightley

Keira Knightley was joined by husband James Righton at the event. The British beauty opted for a bold attire that reminded us of Marion Cotillard’s beaded dress in Cannes.

This Chanel dress is from the brand’s Resort 2015 collection. It features a beaded bodice and a skirt with floral appliqués.

We would have loved the dress more without the white fabric layer on the bottom but Keira carried it pretty well.
