Some years ago a TV programme, revealed the truth about Marks and Spencer Knickers. The cloth was made in one country, the elastic in another, they were mostly assembled in a third. with just the final trim and label put on in the UK. That however made it possible for them to put a "Made in Britain" label on them. Not long after that M&S gave up all pretence and just have thing made abroad. Sadly that put my Mother and Sister out of work as they were working in a Factory in Bo'ness producing for M&S.
Sadly there are not many that can afford hand made products, which is mostly what is made in Scotland. The days of it being economic to mass produce in the UK even "Gold Brothers" acrylic kilts are long gone.
