Can anyone help? I'm looking for a very thin fine hoodie- the same sort of very fine floppy jersey that modal pj tops are made of- It is to use as a base layer under a tshirt - but it must have a hood. Running/ yoga exercise clothes are not the right feel- I want the softness and very thin material- not shiny/ stretchy like exercise clothes- has anyone seen anything like this? Maybe even a hooded pj top would do...
