Noticed a few posts about connecting the pieces, front and back. My suit was not foam, but if you wanted some additional items you could use to connect front and back pieces like chest/back or even helmet. In addition to velcro you could use earth magnets, drawer latches and/or some hinges depending on the pieces you are connecting. Granted velcro is cheaper and easy to use, thought I would throw those pieces out there in case you have some heavy pieces or problems with velcro rubbing loose. I have used all the pieces in at least one part of my Cybus style suit.
