I'm having some issues on my AP armor with the buttplate. I'm a skinny guy and so my butt sticks out when the armor is snug like I did on my ab-plate. It hangs ok although rides up a bit when standing up-right but when i bend it sticks out on the top and overlaps sometimes cause my butt is pushing it out.   I'm not sure if i should make longer elastic and make it hang lower (its under a half-inch from the back-abs right now) or maybe make the strap between the codpiece/butt longer and looser
