I'm talking here about bare minimum survivor kit :) [also I'm not from US so prices are lower here I guess]

Even worst and cheapest possible suit ["slim fit" preferably] is still making you looking better than 95% of people around - as they don't know the difference.

Modern nylon can look and feel GOOD if mixed with viscose. Such suits are ridiculously cheap. I have few of such suits, and to be honest - people(let's say ladies on the street) do not see the difference between those and 90% wool ones. :)

Same goes with cheap Chinese shoes. If you take care of them - they will last even if they are shit. For example I still wear 100% leather shoes I bought for 40$ over 4 years ago. I just take great care of them and I fix them on my own.

My thesis is: get cheapest stuff and make most of it. Same as: https://en.wikipedia.org/wiki/Minimax
