No the neckerchief size has never changed. Some individuals, like an old mate, used to alter them so they were much slimmer and ironed flat rather than rolled. They were still the same length.
I have a very old US sailors white uniform that is made of cotton and not polyester which feels awesome when wet. I LOVE their Dress Blues with those 13 button pants and have enjoyed this wet in bath and shower and also in mud
Nice always liked the us navy uniform I put 2 ties together to create the large knot and love getting it wet and messy sand love getting the wide blue collar wet and messy also
