"La Perla thanks Pedro Lourenço for his vision executing the first phase of evolution for the brand towards a complete lifestyle proposition," read a statement from the Italian lingerie and beachwear label.
Haart - who will oversee the label's lingerie, sleepwear, beachwear, accessories and menswear lines - will make her debut in September, presenting La Perla's new ready-to-wear collection at a presentation in Milan. She previously collaborated with the brand on accessories edits for its spring/summer 2016 and autumn/winter 2016 collections.
"Julia comes to La Perla as a trusted advisor, bringing consideration of the female body and experience of wear and beauty as a primary focus," said chairman Silvio Scaglia. "La Perla's spring/summer 2017 collection will be a revolutionary one, not just for our brand but for women's fashion in general, thanks to a strong mix of our atelier's savoir faire, a woman who is extremely talented as a creative director and the best materials in the world. Julia's work is emblematic of the La Perla lifestyle and I am excited to work with her on this new cornerstone of the brand's history."
