The city of Nice has lifted a controversial ban on burkinis - the latest French seaside resort to do so, in line with a national court ruling, reports the BBC.
Bans on the women's full-body swimsuits have also been lifted in Villeneuve-Loubet, Cannes, Frejus and Roquebrune.
French Riviera mayors imposed the bans, but they were overruled last Friday by France's top administrative court.
Critics see burkinis as a symbol of Islam and potentially provocative after the July terror atrocity in Nice.
But on Friday, France's Council of State ruled that the ban in Villeneuve-Loubet "seriously and clearly illegally breached fundamental freedoms".
The human rights lawyer who brought that case said he would take each town to court over their burkini bans.
The Collective against Islamophobia in France (CCIF) and the Human Rights League (LDH) challenged the Villeneuve-Loubet ban, turning it into a test case.
In recent days courts in several French Riviera resorts have annulled their bans - even though local mayors had vowed to keep them in place.
