Zoë Kravitz showcases Jessica McCormack jewelry at London summer party

Zoë Kravitz co-hosted Jessica McCormack’s summer solstice party in London in a one-shouldered white silk dress that let the jewelry do the talking. Carey Mulligan joined her at the event, which was held on June 25, 2026, and the cast of guests also included Jodie Comer, Alexa Chung and Poppy Delevingne.

Kravitz’s look worked because it refused the usual bridal formula. The knee-length dress read clean and modern, almost spare, so the accessories carried the mood: curved silver bangles, a matching ring, small drop earrings and a rounded arm cuff punctuated by a single diamond charm. Silver Christian Louboutin slingback pumps kept the palette taut, while oversized black sunglasses gave the outfit its after-dark edge as the sun went down.

The styling landed squarely in the cool-girl bride lane, where the white dress is less a declaration than a backdrop for jewelry with enough character to hold its own. McCormack’s pieces did exactly that. The brand’s engagement-ring collection includes bespoke and custom commissioning options, a detail that gives Kravitz’s appearance a sharper editorial charge in the midst of ongoing speculation around a ring linked to the jeweler. McCormack has not confirmed designing it, but the connection has only burnished the brand’s aura around Kravitz.

That relationship was already built into the brand’s own framing. Jessica McCormack identifies Kravitz as its first ambassador, collaborator and muse, which makes this look feel less like a one-night styling exercise than a chapter in an ongoing visual partnership. Worn this way, the jewelry did not simply accessorize the dress; it defined it, turning polished silver and a single diamond accent into the main event.

For summer bridal events, city-hall ceremonies, engagement parties and second looks, that is the lesson in the Kravitz formula: choose a pared-back dress, then let sculptural earrings, a ring with presence and one emphatic cuff do the narrative work. In McCormack’s hands, the effect is not traditional bridal sparkle but something more modern and more wearable, a white-on-white study in restraint with just enough gleam to feel consequential.
