Many witnesses, when asked what someone was wearing, can be vague or general in their answers. How many bulletins have you seen that say something like "the suspect was wearing jeans and a T shirt" etc.

But when the suspect is wearing something more out of the usual such as a kilt they get much more definite.

I look forward to the day when they also have to name the tartan that they were wearing in order to narrow the field of suspects down.
