I've been packing sometimes with a balled up sock for about 7 years and just got my first real packer, but don't own a slim enough harness for daily wear. Wanted to share my quick n easy fix, which worked for a formal ceremony today.
I've looped a thick rubber band twice (around the balls and shaft) and slipped a safety pin through the top. This would probably also work with a hairband. Then I positioned it, pulled up my underwear (I'm wearing thin trunks without much of a pouch) and pinned it to the front from the inside so it sat where I wanted (I prefer it low).
Stayed in place under chinos all day fairly well. Will be DIYing a similar method that's not attatched to my trunks but to it's own band to avoid it getting pulled out of place.
