BHV Marais has new owners, and their first act was to reverse their predecessor’s last one. A management buyout led by chief executive Karl-Stéphane Cottendin has acquired the Paris department store from Société des Grands Magasins and aims to have Shein gone by Christmas, seven months after the ultra-fast-fashion giant opened on its sixth floor. Cottendin calls the episode “a strategic error.” He is right, though not for the reason the words suggest. The mistake was never political. It was a theory of what a 170-year-old store has to sell.

The trade press reads this as a backlash survived and a landlord swapped. Both are true; neither explains the speed. A backlash is a mood, and moods pass. A store sheds its signature partnership in seven months only when the partnership has started spending the asset that made the store worth a partner.

What SGM placed on the sixth floor was not a tenant. It was a loan of the store’s name — a name that, in France, still tells a shopper the house has weighed what it carries. Shein did not need BHV’s footfall; it needed BHV’s blessing. It got neither for long: within a week of the November opening, Sandro, Maje and Claudie Pierlot shut their concessions downstairs. The labels that lend a store its taste do not wait to see how the experiment ends.

Over the months that followed, roughly a hundred brands had gone: some in open protest at Shein, some over invoices SGM had stopped paying on time. The two reasons are one reason. A store that cannot keep faith with its suppliers will not keep their custom, and a department store’s standing is only ever on loan from the brands willing to be seen inside it. They called the loan.

Then the institution above SGM recoiled. SGM had run seven regional stores under the Galeries Lafayette banner since 2021; the day before Shein’s opening, Galeries Lafayette cut the affiliation, calling Shein “in total contradiction with the values and positioning of our brand.” Note the structure. A department store tried to lend Shein its legitimacy, and the older house whose name it operated under declined to let its own credibility stand behind the loan. Legitimacy does not travel down a franchise agreement.

The walls went too. Galeries Lafayette sold the BHV building to Brookfield in January; SGM, which had held an option on the walls it operated within but could not finance the purchase, found the BHV chapter had closed without the real-estate dimension that had justified it. The building found a buyer; the goodwill inside had never been SGM’s to sell. That belonged to the brands now walking out.

The sixth floor was always for rent; the name above the door was not.

Cottendin can put Shein out by Christmas. Recalling the brands that walked will take longer; the year has taught his store that credibility is the only stock it cannot reorder. The hundred who left did not leave a forwarding address.
