go to your local hardware and buy a rivet gun, go home, flatten a md can and measure its thickness. go back to the hardware store and but rivets made for that thickness of material.
rivet in perpendicular rows, collarbone to just past your waist.
realize this takes more cans than you thought and go on a md binge.
lace together from breastbone out, using the same rivet gun, checking frequently for size and adjusting for your girth.(don't just stand there, move and stretch, armor is for fighting,not just posing)
repest, repeat, repeat.
the most boring part will be getting them all perfectly clena inside, but if you don't you will look like a necrofighter from all the flies swarming you.
and dont worry, pop=rivets aren't dangerous or difficult, and you can usually get a good gun for $20-$30. good luck, email me if you need more help.
alternative: use only tops for a cool look
alt: use sides, with top an bottom removed, but get rubber cement to coat the edges with(preferably the good shoes reapir kind, not the 3rd grade art project kind) so you don't cut yourself into 451,742 small pieces.
then walk around realizing why there is a big negative to move silent chakcs in armor.
