Britain’s fashion brands have long looked to the United States for a chance to supersize sales — with varying degrees of success. After all, the United States is much larger, more diverse and already has plenty of fashion labels to choose from.

But the pandemic led many Americans to spend more time online seeking out new brands, including ones from across the Atlantic. Now, three cultish London brands that experienced new popularity during that time have decided to set up shop on the East and West coasts.

Hunza G

You may not have heard of Hunza G, but chances are you’ve seen the label’s signature wrinkly-crinkly, super-stretchy Lycra swimsuits on the likes of Rihanna or Hailey Bieber or Kim Kardashian.

Established in 1984 by designer Peter Meadows, Hunza was known for tight and bright dresses that were a fixture on the 1980s club scene. Whitney Houston wore a lilac tank style for the “I Wanna Dance With Somebody” video, and Julia Roberts wore a blue and white cutout version for her first scenes in “Pretty Woman.” Almost 30 years later, in 2015, and after a period out of fashion favor, the label was revived under a new co-founder and creative director, Georgiana Huddart.

Huddart quickly began creating swimsuits in a distinctive knitted seersucker fabric that is thick and body-hugging and made on a circular loom for ultimate stretch. The material molds itself to fit women who are different sizes on top and bottom and comes in one size for U.S. sizes 2 to 12.

Prices range from $200 to $300 for women and $90 to $105 for kids, and the swim collections include pieces suited for pregnancy and children’s designs.

Rixo

Established in 2015 by Henrietta Rix and Orlagh McCloskey, Rixo has become a go-to brand for desk-to-dinner outfits and wedding-guest dresses for many affluent British women. Vintage-inspired looks in distinctive and cheery prints are the Rixo trademark, often with flattering necklines and sleeves on pieces that look pretty and aren’t necessarily part of the mainstream flow of seasonal trends.

“We came to market with a small range of hand-painted bias-cut silk dresses at a time when the fashion aesthetic was very punky and cool and there weren’t many labels offering feminine vintage flair,” Rix said. (Prices start at $250 and average $500 for collections, which arrive in monthly drops, although bridal pieces can cost as much as $2,000.)

The appeal extends to celebrities like Margot Robbie, Selena Gomez and Ashley Graham, as well as Catherine, the Princess of Wales.

Me+Em

If you ask Clare Hornby who the target customer is for Me+Em, the contemporary womenswear brand she founded in 2009, the answer is “busy women.”

Not an unheard-of response, perhaps, but Hornby, a former advertising executive, has emphatically cornered that market — in Britain anyway. Simple and versatile pieces include crisp white T-shirts, tailored blazers and carefully flared pants, chic knits and the occasional elegant dress or jumpsuit that often look more expensive than they turn out to be. Prices range from $40 to $600, with some higher-end pieces like silk dresses or shearling coats around the $1,000 mark.

“Our shoppers tend to be socially busy, working and juggling a family,” Hornby said. “We give them the wardrobe solutions that they need but don’t have time to hunt for.” High-profile fans include Queen Camilla, Princess Beatrice of York, Helen Mirren, Amal Clooney, Gillian Anderson and Cara Delevingne.
