The flagship store on Paris' Avenue des Champs-Elysées will need to be completely refitted before it can re-open, firefighters told Women's Wear Daily.
The cause of the fire, which started on the second floor at 7 a.m., is not known.
Most of the merchandise and furniture inside was completely destroyed.
No one was injured in the fire. It's unclear whether anyone was in the store when the blaze began.
Abercrombie hasn't said when the store will re-open.
