I shop on this site regularly, believe it or not. I've placed nine orders on WD so far and I plan on buying from them again in the future. Their customer service is hit-or-miss sometimes, but if you come off as polite then they'll give you the same respect in return. They've answered all of my questions, handled all of my orders quickly, and even helped me through with their bonuses/discounts.
From my experience, Wholesale-Dress is one of the few 'popular' Asia fashion sites that never overestimates their product weight. Even their shoes, heels, coats, and bags are nicely priced and average quality. This site also has reviews from users that give you a good idea of what you're getting. Just keep in mind that you get what you pay for. Use your common sense when buying online and judging from similar pictures, really. I'm nine orders in with Wholesale-Dress and now I KNOW what's gonna be cheap and what's going to be an amazing steal. You sort of train yourself to know what's gonna be crap or not, just from judging things. Bottom line is: when you're shopping on this site, the minute you start to doubt their product then don't buy it. So far, all of the things I've received are exactly the things I want. I even have two pairs of Black Milk galaxy leggings that I bought for $12 USD from WD.net!
Trust your instincts, and have a little faith in the customer service because it's not all that bad. Because there is SO MUCH MORE WORSE OUT THERE, just letting you know.
Also I think most wholesale shoppers don't realize that WD has a US warehouse, but with a limited selection. Still, it's extremely fortunate when you buy a good number of their clothes and shoes and don't have to pay the ridiculous shipping amount. So if you're a first-time buyer and live in the States, I definitely suggest you start from their US warehouse before you brave their China stock.
I've ordered from both warehouses frequently! They all arrive nicely, and they package their products in individual, personalized zip lock bags? Well, not the kind you'd store food in, but it's nice that they just don't wrap their things in saran wrap. I always use FedEx as my shipping option. It's safe, tracked, fast, and you usually have to sign for it. Which is something great to have, in my opinion.
If you need any sort of help from ordering to product quality, I can gladly post pictures or videos of all my clothes, bags, shoes and etc.
