Fodor's Expert Review Mavi

Turkey's homegrown jeans company, Mavi (which means "blue" in Turkish), has come a long way since its founding in 1991, with stores now in dozens of countries. The flagship Istanbul store near the top of İstiklal Caddesi (there are two other, smaller, branches farther down the avenue) carries the brand's signature jeans and casual wear, as well as a collection of hip Istanbul-themed T-shirts created by different guest designers.
