I'm finally going to do my first dual martial arts game tomorrow, but since I'm a crazy P person, I'm nervous right now and I'm reading the instructions, but there's nothing specifically about clothing.
 
Experts who will answer a few questions below.
 1. Can I just wear comfortable sweats or something like that?
2. Do you wear underwear without taking them off even when wearing surgical gowns? Is it okay to put on a patch or something??
3. Are surgical gowns meant to be worn after taking off all the clothes you were wearing..?!?

They said that since the surgery only involves natural adhesion, they first put you to sleep and then wake you up after local anesthesia!
