I have bought children's clothing and women's clothing on ThredUp. I like the pictures and descriptions, and have gotten good quality, inexpensive clothing. I really love the referral credits!
SHIPPING IS OUTRAGEOUS! It's $2.99 for your first item. THREE DOLLARS for ONE item! Then, $0.99 for each additional piece. Not only that, but the shipping is TERRIBLY SLOOOOOOOOW. All my orders have come through FedEx, and I have other items come to me through FedEx that don't take forever, so I'm sure FedEx isn't the problem. I placed my last order (for two items) or 6/16. They left ThredUp on 6/19. Today is 6/27 and FedEx estimates my stuff will be here on 6/30. Two weeks? It seems like ThredUp is charging a premium for shipping, then purchasing the very cheapest/slowest shipping available to them.
The clothes are great. Shopping is easy and fun. Be prepared to wait forever for your stuff to arrive!
