While wandering around the Warsaw uprising museum recently i spotted this (apologies for the poor photo, the light was very poor and it was behind glass), a new one for me as i have neither seen or heard of these before.
There is very little out there on the net but i understand these to be an SOE jump suit, they were nick named "strip tease suits" and only used during the jump and then discarded.

One of the few photos i have been able to find on the net!..
