It has its pros and cons, so if you don't like shopping online/worry about return policies, you should definitely be careful with what you buy.
I bought a jacket from this site about a month ago and I just now got my order in today. While I understand that it's shipping from China, I've ordered things from all around the world and often have received those items before things I've ordered from my own country.
That said, I didn't need my purchase by a specific time, so the wait wasn't a huge deal to me.
My issue is that the sizing was off. DEFINITELY BE WARY OF THE SIZING.
The particular jacket I bought was supposed to fit a little large and long, almost to be worn loose like a cardigan. The starting size already said it was large (I think it was something like 40"-42" across the chest) and, since I'm a bit busty, I decided to go one size larger so I could for sure zip the jacket up if I wanted to.
What I expected from the jacket was a long, loose-fitting 1X-2X. What I got was a jacket that stopped at the top of the thighs and fit like a medium.
I was at least lucky that my sister was actually able to fit the jacket. So, while I am a bit disappointed with the sizing and in the fact that I won't be able to wear it, at least I don't have to worry about paying for return shipping.
The actual jacket wasn't as cheap as I expected it to be. It was about what you would expect for $15-$25; on par with something you might buy at a Forever21, maybe at Old Navy.
The material was light, but warm enough for a chilly day.
The site itself is okay, has a pretty large variety of items, and the prices are pretty solid. From the other reviews I've seen, all the other items you can buy, like jewelry, watches--anything aside from the clothes, it seems--seem to be pretty consistently satisfactory.
So, TL; DR: be careful of the sizing, just know you get what you pay for.
