Antique corset (XX or XIX?)

Hello, I am not an export in antique lingerie so… can anyone help me dating this corset (coming from France)?
I thought 1900-1910, but the seller told me it’s from XIX.
I am not sure if she’s right…

 

I think late 1910s because it is designed for the waist and hips, not the bust, which would have a brassiere. The hook on the front is for keeping the petticoat from riding up and thickening the waist and they are still wearing a couple of petticoats into the late teens. My guess would be 1918ish.

 

How did the petticoats waistband fasten to the hook? Just by hooking onto the waistband or another way?
I have never seen any antique petticoats with button holes to accommodate the hook.

They don't fasten to the hook, the top band of the petticoat is kept from riding up by the upside down hook so it doesn't add volume to the actual waist.

 

That makes much more sense! It is a stop gap piece.

Thanks for the clarification.

 

Thank you very much for the explanation Jonathan, now it makes all more sense. Also thanks for the detail about the hook, I really didn’t understand its use. Really helpful!

 

P.S. I have only ever seen the hook on European-made corsets - not sure if they ever appeared on American ones - they might have, but I haven't handled any.

 

The former owner told me she bought this corset in France indeed.
I have also noticed that the corset has no straps for stockings. This was one of the reasons why I was in doubt about its dating.

 

Garters could be added - some women preferred to use roll garters instead of clips.

 

Thanks again!
