A child's outerwear garment is disclosed that facilitates quickly and properly putting a child into a child's safety car seat and fastening them therein with the seat's restraint system according to NHSTA recommendations. The outerwear garment also facilitates quickly and easily removing a child from the safety seat. The outerwear garment has a rear portion that is worn like a vest but does not cover the chest area of the child so that the belts of the safety seat may be properly positioned and adjusted on the front of a child in the seat without the presence of the front portion. A front portion of the garment is then attached to the rear portion and it helps retain the position of the belts of the safety seat and helps prevent a child from wiggling out of the belts.
