Help dating vintage Parisian silk slips

[Margotcara]

I have three vintage silk crêpe de chine slips, they belong to my grandmother who is from Paris and she inherited them from her mother.
The handstitched label says they are from ‘La grande Maison de blanc’ which I know was a very fancy department store that sold lingerie.
(There is a piece in the Royal Collection).
I can’t find any for sale online or much information about lingerie from the label.
Any help dating them would be really appreciated!

Wow, I thought they were late 1940s/early 50s, thanks for your help!

Lovely slips! They appear more '40s -50s to me. It's a classic style that was popular for quite a long time and '30s slips tend to be longer so I agree with your late '40s to early '50s dating.

These look 1940s to me. That label is unusual, I wonder if there may have been a vintage shop that made that label and had it sewn into its garments.

Thanks for your replies! I definitely think they are mid to late 1930s now. The embroidery and bows look very 30s to me. During the war in the early 40s I think they might have made more utilitarian, simple garments than these (but I might be wrong!) After more research, I found that ‘La Maison de Blanc’ was a luxury lingerie boutique, I think the sewn in labels must have been because each slip was handmade and not mass produced.

Postwar 40s at the earliest, but I think more likely mid-late 1950s because they are good quality, and likely made for a more mature, established client. The cups are cut with a seam which suggests a more torpedo shape - typical of that era's silhouette, and the skirts are cut quite full, also more typical of the 50s.
