The designer has accused the 36-year-old reality star of selling borrowed runway samples on her Kardashian Kloset website — but we hear Kardashian was never told to return the items.

“@khloekardashian why are my runway samples I loaned you being sold on your website?” Cowan wrote on his Instagram Story on Sunday.

An electric blue midi dress by the brand was initially listed on the Kardashians’ resale website for $1,300. A similar style from Cowan’s Spring 2020 collection retails for $1,950.

Cowan also alleged that he has reached out to Kardashian’s team multiple times, but has been ignored.

“We’ve emailed 3 times and had no response,” he said.

But Page Six Style has learned that Kardashian was never told she couldn’t keep the gown.

“The dress was gifted to her through her stylist without a mention of a loan and it was never asked to be returned,” an insider told us.

Strangely, the dress was later removed from the website on Monday afternoon.

A rep for Christian Cowan had no comment.

The Kardashian-Jenner family has been criticized in the past for selling their hand-me-down clothing on the Kardashian Kloset site, with seemingly no charitable aspect involved.
