Twice now (about to be three times) I've ordered from Light in the Box and products have been good. I stick to pieces of jewelry which have been just fine so far (Think Claire's quality if you're in the US, just a few bucks cheaper), some sandals (fit perfectly when I converted the sizes from US to EU), and two shirts. Also ordered purses and have loved them so far. Both have come neatly packaged and undamaged by post.
Here's the kicker, the sizing on clothing seems to get everyone. Tried to order a XXL and that was way too tight. I have another order with two XXXL shirts and I hope it works per the conversion chart that Light in the Box has provided on the site.
The shipping is a nightmare and I don't buy anything that isn't marked "Free Shipping" because it simply isn't worth it. It's going to take a month or more to arrive so might as well get it as cheap as possible.
