I've never worn camo when I've played, always gone with Khaki SFU trousers and a black T-shirt/fleece. Now I'm looking at the polish woodland stuff and really liking the look of it
Singapore Armed Force camo is excellent for tropical rain forest use. but well, you don't live on a tropical place, don't you? so i'll recommend PennCott to you. really nice one. for urban, grey is good. i actually want a Silent warrior combat shirt in LCRP camo from Molay Tactical (molaytactical.com) they have the pants in the same color too, in decent price.
Rather expensive and only available as a Denison smock or postwar Belgian gear but it will be rare to see anyone else in it and it is rather effective. Looks best with a Sten gun and P37 webbing
