I followed their brand guidelines very closely and sent in clothing including several pairs of pants which had NEVER been worn. The only item they accepted was a dress which had actually been worn several times. I was extremely insulted at the implication that the clothes were dirty or stained, especially considering that many of them had NEVER BEEN WORN. I would not be surprised if my items ended up on eBay as others here have suggested. I requested my items back and offered to pay, but was told that they had immediately been donated. Really? Within several hours? There are two possibilities, either Thredup is thieves or morons. Or possibly both.
