Based on this information, these dolls were "cabaret souvenirs."
The tag reads, "Le Perroquet l'Arlequin" "Paris"

I've done some Internet surfing, trying to get some information about The Dolly Sisters and these dolls. Here is a link to Netlex News containing more information on The Dolly Sisters. Don't you think these dolls look like them?
Click Gary Chapman to access the web page on The Dolly Sisters. He wrote a biography about them, called "The Delectable Dollies - Icons of the Jazz Age" in 2006. Also, click this link to view another web page from his site.
Here is another Lilith that Sue is restoring. Note the unusual hands. These are not typical of most boudoir dolls. This particular doll is not the stereotypical boudoir doll.
Sue took this photo to show the difference between the Lilith doll on the right and the Anita-type doll on the left. The Lilith doll in the middle has an Anita-type body, although of the era, not original to her so Sue made her an appropriate body.
Here is the back of a Lilith that shows the maker's mark. This is always a thrill to see a marked or tagged doll.
What I admire the most about Sue's restoration work is that she marks the bodies she reproduces. This lets people know it's not original to the doll. However, what is even more wonderful is that she keeps to the era. Even if she must use newer material, her goal is to keep true to the doll. In effect, Sue is truly restoring. 
I've posted a similar photo of Marie Prevost and her French boudoir doll in previous posts, however, this one is a closer shot. This is an old publicity/fan handout.
