Where on earth does that figure come from?
A few years ago when I had a little retirement job with the UK’s second biggest airline, we went from having an allowance and buying your own to a supplied set of kit. This consisted of 2 pairs trousers, jacket, six shirts, tie, rank markings and a foul weather coat. With bulk buying they got it down to £70 total.
it was quite good quality and in spite of the label we found everything could be washed in the machine (I never tried the jacket).
