I wasn't aware I sounded...aggressive? Please understand that it was hard to tell what you meant, as a lot of people frequently post regarding battle ready gear.
Conventionally, people just use snaps and buckles to keep their suit on. If you need padding to keep it from moving around, then it sounds like it's too big?
There are several threads on how to snap down, strap and other wise attach armor to clothes etc. Some are in the 'Under Armor' section and others can be found with the search feature.
