SHOP TALK: Yohji Yamamoto's exhibition at Antwerp's MoMu museum last year was a sign of bigger things to come. Next up, the designer is set to open his largest store yet in the fashionable Belgian city. The 10,000-square-foot boutique, slated to open in September, will replace the museum's restaurant plus some temporary exhibition space. The designer's Yohji Yamamoto, Y's and Y's Mandarina lines will be housed in the store, as will his soon-to-be-unveiled jewelry collaboration with Japanese pearl specialist Mikimoto. The designer also has made space for a lecture area for fashion students from the Flanders Fashion Institute that's housed in the same complex, as well as for his daughter Limi Yamamoto's collection.
