Protesters accuse Cavalli of replicating a sacred Sufi symbol on his Just Cavalli scent.
2,875 supporters added their name to a Change.org petition started in London.
Earlier in the year, the London branch of the Maktab Tarighat Oveyssi Shahmaghsoudi School of Islamic Sufism (MTO) registered a cancellation action against Cavalli’s logo with European and US trademark offices.
The MTO, which has its roots in Iranian Shia Sufism and dates back 1,400 years, has several international centres. It owns the copyright on the symbol which it describes as representing “peace, purity and the name of God.”
The Cavalli company denies that its Just Cavalli logo is based on the MTO’s, describing it as “clearly very different.”
Sufi students have held protests around the world including in New York, Washington, California, Dusseldorf and London.
