I honestly have bittersweet experiences with yesstyle. I love their huge selection of clothes, I love that it is so easy to browse the website, and even that you can filter the results by down to the color of the items.
But there have been two times that I have been dissatisfied with yesstyle. One time I bought a dress, when the dress arrived it was defective the sewing was just sloppy. The dress had some ruffles that were supposed to be in the right in the middle, and they were more left centered. Tried to return it but they made it almost impossible. I needed their approval! I had to send photos and the customer service representative still said it was not defective! I tried until I finally managed to get their approval.
Other time I purchased a dress from the sale section and had some suspicious stains. Couldn't even return it or exchange it or whatever because the items in the sale section are final sale.
These two incidents have prevented me from shopping there again. I usually visit their site just to look at the clothes, but with no intention of buying, and since I discovered Taobao I've found that they sell stuff from Taobao at ridiculous markups!
Here are some examples
On Yesstyle this bag retails for $50 USD. Currently it is on sale for $40 Here
Same bag, different color on Taobao for 69 Yuan (approx $11 ISD) Here
The laceup boots, they are basically a knockoff of Liz Liza Winter 2011 Boots. Original price $62 Here
I Bought the same ones for about $15 USD Here
This Blazer retails for $75 on Yesstyle Here
Found it on Taobao, even modeled by the same girl for 139 Yuan (approx $22 USD) Here
Regular retail price is $32. It's on sale now. Here
Modeled by the same girl again. 83.20 Yuan (approx $13 USD) Here
Basically if I would've Purchase those four items from Yesstyle the total would've come to $219. While on Taobao would've been $61. HUGE difference.
Honestly, I don't think I will purchase from yesstyle again. Unless it is something very hard to find.
