What ive found from mine, the torso/upperarm/wrist didnt need any, apart from some thick low density foam in them to sort of hold them in place. The thighs and calf armour is currently held together with a flat fabric strip which runs down the outside of my leg attaching using velcro but i plan to use Epoxy glue,D-Fasteners and velcro straps in the future. This attached to a utility belt which goes underneath the secondary belt which holds the armour pieces for the belt. The boots are made around an old pair of Primark shoes so just go on like normal. The helmet i have padded with foam making sure to leave the ears and mouth unobstructed. I also wear some thin under armour long sleeve vest and leggings with an open face balaclava to complete the look. I hope this helps. Happy to respond with images if helps.
