Tabitha Simmons EXCLUSIVE AT NET-A-PORTER.COM. Designers Tabitha Simmons and Johanna Ortiz have teamed up once again to create another covetable footwear collection - this time, the result is an exclusive capsule for our Colombian Collective initiative. These floral-print 'Vera' flats have been made in Italy from smooth silk-satin and have an elegant crepe de chine ribbon that knots at your ankle into a pretty bow. The pointed toe and curved vamp add such a sophisticated, polished feel.
