Right after supporting her friend Jonathan Anderson’s womenswear debut at Dior in Paris, Greta Lee bolted to London Wednesday to attend a press event for her new movie, “Tron: Ares.”

The always sartorially on-point actor wore a dress by Diotima, a New York-based brand headed by Rachel Scott, who also recently took over as creative director at Proenza Schouler — another label Lee wears consistently and has worked closely with.

The look — pulled from Diotima’s recent Spring 2026 runway — is a dark grey jersey knit maxi dress with navy-blue, velvet-like, ridged piping around the neckline, shoulders and waist. The stark contrast between the two fabrics not only adds visual interest, but it also loosely resembles the instantly recognizable contours of the Tron bikes from the franchise’s past films and beloved Disney World ride. (We love some subtle but effective method dressing.)

Lee, with the help of stylist Danielle Goldberg, opted to let the garment speak for itself, wearing zero flashy accessories or jewelry (with the exception of her minimalist silver wedding band) to complement the dress.

Strappy black sandals, ballet slipper-pink nails, peachy blush-forward glam and a slicked back bun completed the full look.
