Models Toni Garrn and Karlie Kloss

If you’ve ever wondered what it would be like to walk a mile in Karlie Kloss’ shoes, here’s your chance. Well, if you’re a size nine at least. The model has ponied up and donated two pairs of shoes and lots of clothes from her personal wardrobe for fellow model and friend Toni Garrn’s second-annual Supermodel Charity Flea Market.

This is the German model’s second time hosting the event, which benefits the Toni Garrn Foundation, supporting girls in Zimbabwe. The flea market will launch with a private event at 35 Great Jones Street in New York on Wednesday and opens to the public after 2 p.m. that day. After last year’s demand, Garnn has extended the shopping event for two more days, with additional hours on Thursday and Friday, from 10 a.m. to 6 p.m. 

What is on offer besides Kloss’ shoes? Stylists have donated gowns and accessories, while retailers, such as Forty Five Ten in Dallas, have given boxes of unworn pieces (including a brand-new Azzedine Alaïa handbag). Fashion brands such as Brock Collection and Frame Denim have donated pieces from their lines as well. And with lots of models donating their own clothes, it can’t be any surprise that there will be plenty of quintessential model off-duty looks from Isabel Marant, Stella McCartney and The Row for the buying. Prices at the sale will be up to 80 percent off retail and, according to Garrn, there’s a ton of merch that has never been worn — or barely worn. After all, this is the selfie generation.

“It’s a lot of fun, because a lot of models come to shop from each other,” Garrn told WWD. “It’s such a practical cause as well, because nobody has room for all the stuff they love. We love to shop, but we don’t have any room for it. So everybody’s like, ‘Yes, take it!'”

The charity raised $20,000 last year and Garrn projected this year’s sales will be far greater.
