It was founded by sisters Madame Sylvie Montegut and Baronne Jeanne d'Etreillis under their maiden name, Boué.

In a 1922 article in Arts & Decoration magazine, Jeanne wrote: From our earliest childhood Madame Montegut and myself have craved the beautiful: our desire first took shape in the collecting of dainty ribbons, soft silks, all luxurious materials, flowers, laces – everything that expressed beauty in form and color.

We began by dressing our dolls in the prevailing mode and later found an outlet for our love of the beautiful in creating our own attire.

Signature elements included fine Alençon and Duchesse lace, embroidery, ribbon work, and gold and silver textiles.
