Coveralls (boilersuits), certainly in England seem out of vogue at the moment.
There was a time when you could pop along to Halfords, or Wicks stores, and be greeted by
a nice young chap, dressed in a coverall. I remember spending many a happy hour, browsing
In terms of fashion, I hear that they are "in" again, with many fashion houses producing a jumpsuit in their collection, so that's
your excuse to wear them out.
I remember, when they were "in" during the 80's. All you had to do is
buy a baggy pair, and wear a thick belt, everyone was doing it.
Alternatively, you could have gone along to an army surplus store and bought a flight-suit.
Good places to see guys in coveralls
Road workers, although a lot of them just wear hi-vis jackets or waistcoats.
Lots of broadband fibre optic works going on in London at the moment.
Building sites (generally not in summer)
Cement mixer drivers - some wear orange hi-vis
RAC breakdown assistance engineers - Blue and silver coveralls
Water/Sewer workers - Normally disposable white coveralls over blue their coveralls
Ambulance drivers and paramedics - green one-piece jumpsuit (sadly only a few counties that still issue these).
Lord Mayors Show, only once a year, but a great chance to see loads of coveralls.
Railway workers in orange hi-vis; especially in London at the moment for works on Crossrail/Thameslink especially around Tottenham Court road, Blackfriars and Farringdon Stations
Motor Mechanics in your local garage
Stornoway - isle of lewis
Aberdeen - Loads of oil workers in hi-vis coveralls
Rest of the World
Finland, all the students wear overalls in the universities. The 1st of
May "Vappu", is the best time, when there is a big May day celebration.
