For International Women's Day 2024, Nephthys collaborated with John Lewis and partners to create a series of live art installations at their flagship stores on Oxford Street and Peter Jones in Sloane Square. Her work included live painting of large canvases in the shop windows and creating a 7-foot canvas backdrop for an exclusive networking event, along with custom-designed personalised menus for each guest. The artwork, titled Women Empower Women, embodies the spirit of unity and strength among women.
