The dragons have officially returned to the UK. On Monday night, London’s Leicester Square was transformed into Westeros for the highly anticipated world premiere of House of the Dragon Season 3. While fans are eagerly waiting for the upcoming screen war, the cast delivered pure high-fashion drama on the red carpet, led by a spectacular appearance from Emma D’Arcy.

Emma D’Arcy: Sharp tailoring meets medieval inspiration

Emma D’Arcy, who plays Queen Rhaenyra Targaryen in the HBO series, confirmed their status as one of the most exciting figures in modern red carpet fashion.

D’Arcy arrived in a striking look that perfectly bridged the gap between historical drama and contemporary style. The outfit featured a light grey, oversized structured suit jacket paired with matching wide-leg trousers, completed by a dramatic, draped cowl-neck collar that directly mirrored the medieval silhouettes worn on screen.

The look immediately sparked massive engagement online, with fashion critics praising the balance of sharp modern tailoring and regal, theatrical undertones.

Olivia Cooke and Matt Smith join the London premiere

The rest of the leading cast joined D’Arcy under the London lights, showcasing distinct style directions for the premiere of the new season.

Olivia Cooke chose a contrasting aesthetic, walking the carpet in a dramatic, strapless floor-length dress featuring a rich, textured fabric and a structured bodice.

Matt Smith kept things classic and effortlessly sharp in a dark, slim-fit tailored suit, maintaining his signature sleek red-carpet presence as he met with fans and photographers.

The countdown to Season 3 begins

This London world premiere marks the official start of the global rollout for the new season. With the trailers teasing intense conflicts and massive dragon battles, the cast’s powerful red carpet presence has only heightened the anticipation across the UK and worldwide.

House of the Dragon Season 3 premieres on June 21.
