Hi
the longi, simply made, one size fits all. available in many and varied colours and also more frequently now, in different materials. (silk feels soo good against the skin). Under the duvet one is allowed unrestricted movement of the legs. In hot conditions one is able to use the longi to create a fan effect to provide relief from the heat and also to keep mosquitoes away. The down side is that they do tend to tangle while trying to get to sleep, or come loose.
On the other hand pyjamas do seem to provide one with more security in situations where extravagant movements, or public appearances are likely, such as having to go outside to the car, or go to early morning lectures (ive done it). However under the duvet they seem to rather constrict the legs and also leave less options in hot climates.
my vote has to therefore go to the Mighty Longi. may we see them more often on our high streets, not just on the fabled streets of aldgate or the occasional appearance in a masjid, but all over the uk and then on to conquer the world
