Duchess Meghan is a vision in blue at 100 Days to Peace Gala

After attending the WellChild Awards this week, Prince Harry and Duchess Meghan stepped out again on Thursday evening for another major charity event: the 100 Days to Peace Gala.

The Kensington Palace twitter explained that the 100 Days to Peace Gala is a music event that benefits the Help for Heroes, Combat Stress and Heads Together organizations that all support mental health initiatives.

Meghan looked stunning in a ruffled blue Jason Wu dress that hit just below her knees. She finished her look with navy blue slingback heels, a small clutch and a sleek side-swept hair style.

Prince Harry held her hand on the way into the gala wearing a navy blue suit -- the couple sharing their second sweet PDA moment of the week.
