Sewing with Vintage French Patterns

I have lately been working on drafting beautiful corset/ corselet and garter belt patterns from an old French diagram and it's been an interesting experience.

The measurements are given in centimeters, which I prefer because it makes drafting that much more exact. The only problem is, the pattern was simply noted as being a size 44. A size 44 in 1940's France could mean any number of things and I immediately set out to research exactly what kind of size I was dealing with.

I could find almost nothing and resorted to digging up my French pattern stash (very girl should have one). I have yet to use any of my vintage French patterns yet, as they require some skill and patience, which I'm gaining, and lots of translating of text, which I love doing but seldom have the time for.

I dove into researching the differences between a size 44 by one company and a size 44 by another. All of that is below if you're looking to learn the same thing some time, some day. But first, lets just ooh and aaaaah over some pretty patterns, shall we?

You can see some beautiful Patron-Modèle patterns here at Patterns of History.
Here is what I have been able to discern about French pattern sizing using measurements given by my patterns. I'm posting not because it will be an interesting read, but maybe I'll be able to save someone the headache of figuring it out themselves some day.

THERE WILL BE NO SEAM ALLOWANCES INCLUDED WITH THESE PATTERNS.
