OK, so Tradesy is eBay of the clothing world. Everything and anything can be sold on here, from designer clothing to some lip balm. Shipping is usually between $10 and $20, depending on how large of a bag needed to fit in the garment. I am from a seller's perspective- I've been on the site for about 3 months and have only sold one item. I received the bag to put my item in and shipped it out quickly, within a month I got my payment after the 2% fee or whatever tradesy will take, and the other 2% (I think) safe transfer fee. The thing about this site is that you need to ask questions. The sellers are mostly experienced and will answer any question you have. If not, DO NOT BUY FROM THEM. Most sellers want their items gone. It's a good discount site once in a while. Some sellers can be haggled.
*If you want to look up my closet, feel free to message me. I sell plus sized shorts, size 8 women's shoes, and medium sized tops and dresses.
