Soeurs boutiques

[Pocahauntis]

Hello, I know that Callot Soeurs is a very high end and sought-after label and their dresses are museum pieces. What about other labels that include the Soeurs name--from what I've determined here, Soeurs was (and probably still is) a street where high end boutiques existed. Are other labels that also have the Soeurs name from the 1910s along the same calibre as the Callot sisters?

Soeurs is the French word for "sisters" - Callot Soeurs means Sisters Callot - which is true, as this house was started by three sisters (see https://vintagefashionguild.org/label-resource/callot-soeurs/). If there's a street name in Paris with the term "soeur(s)" in it, it would need a name/word to with it such as "rue soeur xxxx". The word soeur can also stand for meaning a member of a religious order, for which streets can obviously be named.
So the term "soeur" on a label alone doesn't mean much unfortunately, it would really depend on the name to go with it, or if indeed it's part of a street address.
