NEW YORK — Y-3, the collaboration between Yohji Yamamoto and Adidas, opened its first Paris store at the end of August. This month, during the Prêt-à-Porter Shows, Y-3 celebrated its five-year anniversary and the opening of the store. Located on Rue Etienne Marcel near the city’s center, it is not far from Yamamoto’s Y’s boutique at Galeries Lafayette. The 1,700-square-foot, bi-level space is characterized by a contemporary black, white and orange minimalist style. It is the eighth store that Y-3 has opened worldwide. Another is opening in Miami’s Design District later this year.
