Many times the items are not described correctly and that is very frustrating. I bought a cardigan, that when I opened it, was actually a sweater with the buttons sewn on. Also some pants for my son said size 12 and when i've got them where size 12 Husky, way too big for him. Later a bought a skirt described as 27 inch length, when I opened it was 22 inches.
If they described the item incorrectly, they will give you a full refund of the item but a partial refund in shipping, which I find unfair, since you paid full price for shipping and is not your fault they sent an incorrect item.
I'm not buying again from them. I'll stick to thredup.com, never had a problem with them.
