The Gem App

I evangelize this one to anybody who will listen. Gem lets you search a bunch of vintage and resale platforms at once — including Poshmark, eBay, Etsy, Depop, Mercari, and Grailed — so you can megashop clothes secondhand. I try to buy clothes more sustainably than I used to, and this thing makes circular fashion feel like a breeze. Lately I’ve been using it to save vintage flight jackets for my boyfriend.
