Lena Dunham is taking London Fashion Week by storm.

The “Girls” star, 33, made her runway debut during 16Arlington‘s show on Friday, modeling a black A-line minidress adorned with gold lamé leaves and a wrapped leather-like bodice.

“She said it was a dream of hers as a child to walk in a catwalk show and that to walk for us would be a dream come true,” the label’s co-founder Marco Capaldo told Harper’s Bazaar. “We said, ‘no Lena you’re making our dreams come true.'”

Dunham first linked up with 16Arlington when she needed a look for the London premiere of “Once Upon a Time … in Hollywood,” and her stylist approached Capaldo and his co-founder Kikka Cavenati about creating something special. They “jumped at the chance,” the duo told Bazaar, and whipped up a fiery orange and fuchsia frock adorned with sequins and feathers.

“I grew up watching ‘Girls,’ so we were so excited about it,” Cavenati told the outlet. “Lena takes fashion seriously, but has so much fun at the same time, and that’s what we do. We take what we do seriously, but we also have fun with it. We just got on really well.”

“She dresses for herself,” Capaldo added. “We’ve been lucky to work with such powerful women from the beginning — women who are changing the world for a better place and Lena is a prime example of that. She embodies this spirit of power and intelligence. Everything we stand for as a brand, she ticks every box for us.”

Other famous fans of 16Arlington’s designs include Lady Gaga, Ashley Graham and Jennifer Lopez.
