S.T.A.L.E.R loner Cosplay question.

Heyyyy I prob shouldn’t ask this on here but ehh whatever. if anyone knows where I can get stuff for a stalker 2 loner cosplay or has an extra one they are willing to sell? If do please hit me up! I wanna start cosplaying and going to conventions and stuff. I’m a size L for clothing and a size 11 for shoes. I’ll get the BB rifle on my own and the bolts. I’m just having trouble finding the gear, clothing, and shit. I’m moving to mass soon and In my free time I would like to go to conventions and stuff. Thanks and hit me up if you have any Info or willing to sell. If I have too I can go on Amazon and get the patches and the balaclava that’s fine. Have a good day/night
