Emily Blunt continued her designer style streak in a custom look by Stella McCartney for Thursday night’s “Disclosure Day” premiere in London.

The Oscar-nominated “Oppenheimer” actress wore an architectural peplum gown in French lace, woven from organic cotton and forest-friendly viscose in a shade of lilac. The gown also included hand-embroidered Swarovski crystals, mimicking the lilac tone of the dress.

The strapless bodice of Blunt’s gown found subtle inspiration from look five in McCartney’s pre-fall 2026 collection — a corseted piece with exposed boning and semi-sheer fabric with floral lace detailing and a sculpted, architectural design as well.
