The wedding car driver / owner will have decorated the car with matching ribbons and bows prior to arrival at the collection point. If you haven’t made a request for a specific colour then the standard colour will be provided, this will be specific to the car, but typically it is white or ivory.
Other decoration, may have been added, this will be in keeping with the style of the car. You should discuss this with the driver before the event to ensure you are aware of an additional decoration.
Some special requests may be accepted, however this is at the discretion of the driver / owner.
