These skelington pyjamas were orginally only sold for five year olds, on the grounds that they were too frightening for younger children. But when we rang them up and asked for smaller ones surprise surprise "due to customer demand" they were now making smaller ones. Marketing gimmick, I suspect. Still (1998/10/1) available from kids' stuff, +44 117 970 6095 / 0117 970 6095.
