The "Princess Diaries" star told The Sunday Times she began having eye-level conversations with her 2-year-old son, Jonathan, after reading that the Duke and Duchess of Cambridge do that with Prince George, 5, and Princess Charlotte, 3.
She wore her hair up in a sleek chignon to best showcase the dress's delicate floral detail on one shoulder, as well as the late Princess Diana's drop pearl earrings.
Kate Middleton finished the ensemble off with a Mulberry clutch bag. Tonight's 100 Women in Finance gala dinner is raising money for mental health initiatives in schools.
It's been a busy day for the Duchess, who earlier attended a conference on mental health where she spoke candidly about her personal experiences as a mother.
Kate, 37, opted for an elegant powder pink gown from Gucci as she joined female leaders at the 100 Women in Finance charity event at the Victoria & Albert Museum.
The conference was hosted by the Duke and Duchess of Cambridge and Duke and Duchess of Sussex's The Royal Foundation.
She said: "I was very naive myself as a parent, of really just how important particularly the early years are for children's futures".
"It is clear that the positive development of our children is directly linked to those who care for them, teachers, carers and parents", she stated.
