Has anyone ordered clothes from Shein?

I know people who have ordered accessories and little things like that, but not clothes. I need to find a dress to wear to a wedding in September. I would rather order online than go to stores. Shein has a lot of really cute options, but they are all around $20, some are less, so I'm a little skeptical. The reviews seem really good on the website, but I never know if those are legit.

Anyone have experience with their clothes?
