Tory Burch flats
The brand was founded in 2004 and quickly became very popular, since Oprah featured it on her show, making the brand mid range, instead of super expensive, as some people consider it now. Out of all Tory Burch flats, the most popular ones are the Tory Burch Reva flats, who are not only the most popular Tory Burch ballet flats sold, but the most popular out of all Tory Burch items! The Tory Burch Reva flats were first released in 2006, but became so popular Tory still makes new versions of them for every collection.
