Remember the Krazy House well, as it was one of the very few place in Glasgow of that era which sold BIG sizes of gents' clothes.
(I don't mean your piddling 42 inch waist stuff, but serious big boy's gear.) It sold normal sizes as well of course, but if you wanted the outsize stuff you had to go downstairs - out of sight of the Go-Go Girls unfortunately.
When Krazy House closed, another outsize shop opened just round the corner, more or less. I believe the new shop was owned/run by staff from Krazy House, but I didn't think the quality was as good.
