Once upon a time, the Hermès Birkin could arguably have been called the rarest handbag in the world. Urban myths abounded about how to buy and who was allowed to buy; rumors of wait lists were taken as gospel; and the lucky few able to acquire a bag guarded their insider status as if it were a state secret.

Then the fashion resale market took off.

On almost any given day, Privé Porter in Miami has a rotating lineup of nearly 80 of the newest Hermès Birkin bags, in pristine condition and all accessible with the click of a mouse or a tap on a mobile device.

In barely five years, Privé Porter, tucked away in the palm-tree-lined confines of southern Florida, has sold more than $60 million worth of the bags , the company said, to anyone who wants and can afford one, the vast majority of those sales taking place on Instagram.

The digitally native company is part of the booming resale ecosystem , which has seen a growing number of heavily funded and highly trafficked businesses bringing luxury wares to the web, among them the $10,000-plus marquee bags of the 182-year-old Hermès empire. And Privé Porter is not alone.
