Upmarket Dior and Chanel boutiques were among those vandalized by the protesters in early December.
The “yellow vest” revolt, driven by high living costs and frustration at President Emmanuel Macron’s leadership, shows scant sign of abating after two months of unrest, even after he made some tax and minimum wage concessions.
Retailers and hotels were hit particularly hard by the Paris demonstrations in the run-up to Christmas. Department stores and luxury boutiques shuttered their outlets when protests descended into riots in early December, and tourists canceled bookings.
The source familiar with Dior’s decision said the brand was keen to avoid the Saturday street marches.
While turnout at the protests has fallen from early weeks, they have been consistently marred by violence and transport has been disrupted.
Macron’s government has said it will crack down harder on unauthorized protests and get tougher on anyone who loots or vandalizes shops and monuments.
Retailers had by late December lost around 2 billion euros ($2.3 billion) in revenue since the protests began, according to the French retail federation (FCD), which regroups everything from big supermarkets like Carrefour to toymakers and luxury brands.
Department stores and other shops are hoping to make up for lost business as the January sales kick off.

Other high-profile fashion brands including Dior’s LVMH stablemate Loewe are maintaining their Saturday menswear shows.
The French fashion and Haute Couture federation that organizes Fashion Week in Paris said it was working with state authorities to ensure the presentations run smoothly and take place “in the best possible conditions.”
