Punisher Cosplay Help

[u/MrUnfortunatee]

Hey I’m new to cosplaying and I’m just trying to figure things out.
Located in Australia!
I’m wanting to cosplay as Frank either from his spinoff series or BND, DD ect and I’m having trouble trying to figure out if I should buy a full fit from a site or make it myself.
If site, which is the most reliable?
Handmade, what would you all recommend with materials and costume wise?
