A covering of an outer sill of a vehicle, in particular a motor vehicle, has a covering region and a mounting region, which extend between first and second ends of the covering along a direction of longitudinal extension. The mounting region extends in a first direction of transverse extension perpendicular to the direction of longitudinal extension and has mounting elements in order to be able to be mounted on an underside of the outer sill for a mounted state. The mounting region has a lateral edge facing away from the covering region in the direction of longitudinal extension, which has recesses between mounting elements, which are formed such that sections of the lateral edge of the mounting region extend in a recessed manner in the first direction of transverse extension towards the covering region.
