Throughout the development process, the designs are tested by members of the studio, the first ambassadors of this high standard focused on cut, skin feel, and material comfort. It is a work of precision, where every element contributes to the accuracy of the garment, which, like a second skin, follows the body's curves and frees movement.

The last two lace makers of Calais, heirs to a tradition dating back to the 19th century, perpetuate the art of lace with unparalleled mastery. Alongside them, a bobbin lace workshop in Le Puy-en-Velay, guardian of an ancestral craft since 1860, a northern French embroiderer established in 1937, and a Lyon-based silk manufacturer whose expertise has been passed down through three generations since 1956, have accompanied the House for many years. By collaborating with these artisans, ERES is committed to preserving this heritage and promoting the craftsmanship of the decorative arts.
