The larger museum in Marrakesh hopes to attract up to 700,000 visitors a year.
The larger museum in Marrakesh -- where the late designer often retreated to work in the home he shared with his partner Pierre Berge -- hopes to attract up to 700,000 visitors a year.
"Both museums are aimed at the general public as well as fashion lovers. Yves Saint Laurent was a major artist of the 20th century," the couple's foundation said in a statement.
It holds a collection of more than 5,000 outfits and 15,000 accessories the Algerian-born designer created during his 40-year career.
Berge opened Morocco's first museum of Moroccan Berber art in 2011 -- three years after the death of his partner -- to house the collection they built together.
The new purpose-built Marrakesh museum is near the historic riad mansion the couple shared.
Both museums will open in October, with the Paris site housed inside the foundation's headquarters.
