For Montreal-based designer Valerie Lamontagne, the spark of creativity can come from the most unlikely of sources. In the case of her climate-reactive dresses, Lamontagne found inspiration in “Peau d’Âne,” a French fairy tale that begins with a king’s vow to remarry only when he finds a woman who equals his late queen’s beauty and virtue. Pressed to find a new wife, he concludes that his daughter alone qualifies. (Quel scandale!) The princess delays the wedding by demanding impossible prenuptial gifts, including three dresses made from moonbeams, sunlight, and the sky. Lamontagne recreates these fantastic gowns but with a high-tech twist: Each dress reacts—in real time—to changing weather conditions.
