It's cheap, yet expensive.

Everyone says their clothes are cheap, but in reality, some of these clothes are half or less the price if it were actually being sold in Korea. Went there and got a jacket for 15$ at one of the underground stores then found the same one on Yesstyle for about 50$. /shrug/ that's business I guess.
I just get fairly cheap shoes that are pretty and I know I probably won't be able to find elsewhere. I don't trust them with the higher prices (over 50$). I've also gotten their men's jewelry, which is also good.

Other than that, they are trustworthy. Everything I've bought there is good, and I've had no problems with shipping.
