Resale listings of Ivanka Trump's clothing are surging, according to a new report.
Fashion resale website Thredup, which allows people to sell their used clothing, said users have listed 111% more Ivanka Trump-branded items in the first five months of 2017 compared to the same period last year, Fortune reports.
That far outpaces the increase in total listings on the site, which were up 20% over the same time period.
At the same time, stores that accept donated goods, including one Goodwill location, have also noticed a surge in Ivanka Trump-branded products arriving at the store.
One Goodwill employee told Fortune that he's seen an uptick in donations at a location in San Francisco, though a spokesperson for the national organization said it hasn't seen evidence that it's a nationwide trend. Goodwill doesn't track sales of individual brands.
Fortune checked with other charitable stores in the New York City area and several confirmed increases in donated Trump products.
Ivanka Trump's brand has said, however, that sales of its products have increased even in the period since several department stores dropped the line of women's clothing, shoes, and handbags earlier this year.
The brand is now opening its first brick-and-mortar store in Trump Tower in New York City. Until now, the brand sold all its products through wholesale distribution to department stores and websites.
