New label Galvan London has hit the ground running. Gemma Arterton wore a gorgeous midnight blue Galvan jumpsuit to a Vanity Fair/Giorgio Armani party at the Cannes Film Festival (above), while Gwyneth Paltrow wore a black version at an April press conference in Hong Kong (below).

CEO Katherine Holmgren, creative director Sola Harrison, sales director Carolyn Hodler, and design director Anna-Christin Haas established the brand, which focuses on “modern, clean, cool” occasion wear. The founders epitomize the sleek, sophisticated and youthful Galvan customer: Holmgren was head of corporate development at the Serpentine Galleries, Hodler worked at Christie’s, and Harrison was a model before marrying George Harrison’s son, Dhani.

The jumpsuit worn by Arterton and Paltrow won’t be in stores until winter 2015, but in the meantime you can get a very similar hidden corset crepe gown ($1,200) after the collection launches in June. The 18-piece collection, which ranges in price from $675 to $2,050, will be available in 18 stores including Neiman Marcus and Bergdorf Goodman, as well as online at matchesfashion.com.
