An automotive vehicle body has a body opening defined by body structural members and a closure structure mounted on one of the body structural members for swinging movement between closed and opened positions. A sealing arrangement for the closure structure includes a corner bracket structure formed at a front upper portion of the closure structure, a reinforcement formed on one of the body structural members at a front upper portion of the body opening, and a continuous sealing member securely attached to the body structural members and a lower edge of the reinforcement. When the closure structure is in a closed position, the sealing member is in abutment with an inwardly facing surface of a sash member of the closure structure at the location above the corner bracket structure and gradually departs from the sash member in a rearward direction of the vehicle body at the location of the corner bracket structure.
