I can't remember when those laws were changed in the UK, but it didn't stop crossdressing happening it , obviously still in the closet alone but out there were private clubs that provided a dressing service, I say that in the loosest terms , the authorities knew of them but often ignored them.

They were archaic laws then and there's no way it's going to happen again, it wouldn't have stopped me anyway, but it would make a DADT situation harder to avoid .
