However, the Lambeth STh Diploma has a distinctive academic dress. The hood is of black stuff of full Cambridge shape with the lining divided horizontally. The lower half is of light blue silk and the upper half is of white silk, so that the lining appears white over blue when worn. This is an unusual pattern for academic hoods in the UK so some STh hoods have been made of black stuff of full Cambridge shape, lined with mid-blue silk, and the cowl faced with eight inches of white silk. The gown is of the London BA pattern but with blue cords and buttons on the sleeves.
