Decending trousers
We all have to get dressed sometimes, usually including trousers. This time wear oversized trousers with no belt and no underwear. You can only adjust them when talking to someone. No holding on to them or hands in pockets (but some heavy objects in the pockets might be good). You will feel them slipping down. The waist band inches down your tummy and then your bum and hips with every step you take, every movement you make. Then, suddenly and without warning, they drop to your feet. Everything is exposed. Of course you pull them up again, ready to star a new downward decent.
A variation is shortening shorts or cut-offs. After the first
wearing you fold the legs in half so the bottom is touching the
inside leg or crutch. Then cut at the fold. You will have a
perfectly respectable pair of cut-offs. But you repeat this each
time you take them off, halving the leg length each time. So you get
progressively shorter shorts. At what point do they become to short
to wear/ That's up to you.
I have also seen dare in which clothing is made entirely of Duck Tape, loo roll paper or a limited number of napkins. For the textile swimmers there is also the suggestion that the seams of their swimwearare sewn only with water soluble thread.
