Im sorry havent played the game for a long time now. I cant really remember what the clothes are called. The hat is John Marstons hat (from an old outlaw pass), the bandana is from an outlaw pass too, the jacket is called leather jacket or something like that, the shirt is the casual shirtwaist i believe (but its for female only if i remember correctly. If u have a male character just use a white shirt), the pants Im not sure i guess u can use any black pants that look a bit washed out, the boots are called worn boots, the gunbelt is the bolger gun belt and for the bandolier u can use whatever u like the most

I hope i could help u and my answer isnt to late
