Here's another one of my stories  -

The slimmed down Ivy look in Europe had another slightly strange factor in its develpoment apart from the Italian influence...
In London, at least, many of the GIs who wore the Ivy style down the Clubs and around town wore cothes that were slightly too small for them...

Often the clothes were slightly old and the boys' bodies had been built up by military training so that what was once a regular fitting jacket had now become a little snug.

Also the boys would share clothing - Those going out on the town would borrow items from those 'staying home' on the base.
At the Fairford (Oxfordshire) airbase at one time there was even an item known as 'The Jacket' - whoever wanted it wore it! Obviously it fitted some people better than others. 'The Jacket' was a sandy coloured checked sack.

So all the clothes-obsessed London boys checking out the GIs down the clubs would see the Ivy style being worn very close to the body & think that that was the way to do it!

Either this is interesting or it isn't!
