One day, when you wake up, immediately dress in colored leggings (black is forbidden), no panties and no morning piss, only leggings.
You will now go to your daily life, dress anything else you want (as long as it's not bra, panties or pants) with only 2 rules.
You can't take off your leggings for 24h, not even to pee, if you need to, do it with them on and while standing.
And you have to drink 1L of water every hour.
It's easy, right? I want you to send me pictures as proof, one before peeing and one +/- every 6 hours, I'm curious how you'll look after 24h like that
