I do not have a link for this even the Wikipedia item does not list this
But Its worth posting because it was funny and serious at the same time and if you find a Link with the info can you post it Here Thanks?

MY question is what was originally sized from eggcup to Challenge (just 4 sizes) in the Mid 1930s (Possibly 1937?) Item dates back a long time beyond this
But these days the same item has a different scale for precision sizes

I would guess you are describing the 4 cup sizes that Warner came up with for the bra in 1935. They were A-D and I did a little digging and found that they were nicknamed egg cup, tea cup, coffee cup, and challenge cup according to this article.

Cheers Georgia and I had to be careful not to be disrespectful If you understand what i'm saying
like this from that article

THE first concept of a brassiere - from the old French word "arm protector" - appears in US Vogue.

Um Saves banged elbows? And you have to buy 2 Makes a bit of sense!

Interesting bedstor, I have never heard that "arm protector" version. The real term in French for a bra is a "Soutien-Gorge"

A "brassiere " could be a shirt for newborn made of wool that ties up in the back or when the first bras appeared ,women had to lift their arms up high, and get them through the "belts".... so the term "BRASsiere" could have some sense in that way. But "Protector"??? Could be an old piece of equipment for knights and soldiers or something like that. I'll research it.

This seemingly has all the answers, but yes,mozart's comments are spot-on:
