Well if you're looking to go screen accurate than as Rowan mentioned bracket and straps is your go to choice. I'm not aware of anyone of than Mr Nostripes that makes them. All other areas connected with poppers (specific snaps) set and sew in. Those you can get from Ebay UK, maybe some other areas by now. My Anovos OTTK build thread has a list of where to buy if you want to go that route.
