I got nervous after reading the reviews here but I'm all good with Fashion Nova now. I think I understand what happened with some of the negative responses here. #1 The clothes are usually form fitting, so if you're not into that, get one size larger than you usually would. I like my clothes to fit this way, so I got my normal size, which is a large. #2 The quality of the clothes is similar to other low cost stores like Forever 21 and Charlotte Russe. I bought 9 dresses for $10 each. I'm not expecting D&G quality material and durability. The materials are comfortable and similar in quality to Forever 21, so I'm good. So in the end, I approve of Fashion Nova. On the other hand, I didn't need an exchange or refund, so I have no comment on that process. So to avoid needing to return something, just get your normal size or one size larger if you are worried about fit. I usually wear a Large in most dresses, and I bought a large in all but one item, and they all fit fine. Surprisingly, the Medium I bought fit just fine as well, but that was because of the type of dress it is. It's got an adjustable waist and a flared skirt, so it was designed to have space. I was a little worried when I saw that Larges were out of stock, so I ran the risk of losing my $10 on a Medium and ended up being totally pleased with the fit.
