An inexpensive knockoff of the Birkin bag, an exclusive, extremely sought-after leather handbag by luxury brand Hermès that can sell for more than $400,000 US has launched a rousing debate online about fashion accessibility and copycat ethics.

Walmart seems to have been paying close attention to all the hubbub about its so-called "Walmart Birkin" or "Wirkin"—the under-$80 Hermès imitator that skyrocketed to viral fame after it was tracked down by TikTokers this winter. The mega-retailer is responding not by dealing in more dupes, but helping shoppers get closer to the real things.

Walmart is adding tens of thousands of pre-owned luxury handbags, jewelry and watches to its marketplace through a partnership with resale platform Rebag.
