The pyjama conspiracy.

I'm certain, somebody out there is plotting a giant conspiracy. It's what I call ‘the pyjama conspiracy’.

Because really, how come pyjama’s all over the world seem to be eiter:
cute - sleeping with a cartoon on my chest, no I’d really rather not.
sexy - might as well wear nothing, you’ll be just as cold.
or
simply dull - oh, a striped/checked pyjama, how original, yawn, the dullness of it all does make you sleepy, that could be a plus?

Clearly somebody (certainly a man) is organizing this conspiracy in order for women to be typecasted by the night.

Well, I am done with it. I am in desperate need of a comfortable, yet stylish and fashionable pyjama. Really, all hints are welcome here. Anyone?
