From early February, will host a new section titled Lanvin History, featuring previously unseen photographs, archive video footage and original gouaches by founder Jeanne Lanvin. The Facebook page kicked off the festivities on January 1st — Jeanne Lanvin’s birthday — and will post updates every Thursday showing the important dates in the house’s history. the brand’s fans on Instagram can also check in every Thursday for images of objects found in the designer’s office at the house’s historic headquarters at 22 Rue du Faubourg Saint-Honoré in Paris. The room has been preserved and contains archival material like embroidery books, magazines, travel journals and more. Pinterest will showcase boards of images or videos illustrating the DNA, codes and themes of the French brand universe. The first five boards will be dedicated to Jeanne Lanvin, her daughter Marguerite Marie Blanche, Lanvin hats, the logo of the brand and its signature color blue.

To mark the occasion, the house’s original logo representing Jeanne and Marguerite Lanvin has been updated with the number 125.
