Best SHTF clothes question and discussion

[Timelord]

It is a fairly simple issue. Wear what is suitable for the situation, present or prospective and wear what ever blends in with the surroundings, whether that be the physical environment or the mental perceived view of other people in the area. These last two can be very different!
If you think black tactical kit worn in an urban street in daytime is appropriate, then good luck to you. If you think camo gear and a full kitted bergan is sensible moving through urban areas or even some other areas in daylight, then the same again. If you want to intimidate people, then do it only when it is necessary as an element of surprise or you could well just be attracting attention. The attention of a sizable group a far bigger deal than a few individuals. No attention at all is better.
