Oh this thread is so helpful, a quick tutorial in American! I think gumshoes came about from being rubber (gum) shoes or boots.
And I have always wanted to ask, is it right that you'd put panties (knickers or pants to me) on to go to bed in? Under a big tshrtvor nightdress?
Here one would wear a nightdress or pyjamas but with nothing underneath, though a lot of adults, like me, wear nothing at all in bed, other slobby types would just take off their trousers and get into bed with T-shirt, socks and underpants on! Yuk!
Earlier someone mentioned the teeth straighteners, here they'd be called braces, the same as suspenders for trousers.
There were some early knee length trousers still used by the hunting shooting fishing folks that were known as knickerbockers, now called plus fours though I have no idea why.
Brogues would have perforations in their patterning.
Vive la difference!
