I was super impressed with ThredUp. I was a little skeptical of buying used clothing online, sense you cannot see it in person and see the quality for yourself. But after my first purchase I was very pleased! Even things that were marked as a tiny flaw were in amazing condition, I couldn't even notice the flaw that was mentioned. One thing that I was worried about was sizing but if you don't know your size at a store or brand already just check the size charts of the brand on their websites it is super helpful! And the 14 day return policy is plenty of time to get the package and decide that something doesn't fit.
