Selling on Poshmark?

I have a nice paying job, but it’s only part time and I don’t always get the same hours each week so money can be tight sometimes and I saw a commercial for Poshmark and figured that would potentially be a good way to earn some extra cash. I do have a bunch of clothes I’ve been meaning to get rid of, but I’d hate to throw them in the trash or donate them to a thrift store where someone else can make a profit. Do any of you ladies sell on Poshmark? Is it really that simple? What have been your experiences? I think I would be fairly successful since I wear the most common sizes in almost every piece of women’s clothing (I’m a size 8-10 or Medium and I wear a size 8 shoe). I’ve tried selling to Plato’s Closet, but they seem way more picky than I remember them being😂
