tijn is heel chalant?

"Tijn is very casual?" Translated to: "Tijn is casual, wearing a relaxed fit blue jeans, a loose and comfortable grey t-shirt, and a pair of white sneakers. His brown hair is slightly tousled, without looking unkempt, and he is standing in a relaxed posture with his hands in his pockets. He has a calm, but friendly look on his face. The background features a casual setting, a homely living room with subtle off-white walls, a cosy beige couch, and a wooden coffee table."
