Katherine McNamara, an American actress and producer known for her roles in the TV series Shadowhunters and Arrow, attended the Big Slick Celebrity Weekend in Kansas City in 2025.
She appeared in a relaxed yet polished daytime look—a tailored olive-green utility jumpsuit cinched at the waist and paired with white sneakers—blending comfort with casual-chic style suitable for the fan-focused charity event.
The outfit was styled with minimalist gold jewelry, her hair pulled back into a sleek ponytail, and natural, dewy makeup—highlighting Katherine’s warm presence and approachable elegance as she supported the Big Slick Foundation’s family-centered causes.
