I ordered a dress on Jan. 3,2013 and it arrived on Jan. 14. Shipping takes awhile but they do explain that the merchandise comes from somewhere else, then Zulily ships it to you.
I am 100% satisfied with my dress. The size is accurate, the fabric is very comfy and a nice quality for such a low price. The dress looks nice in the picture but I wasn't sure what it would actually look like. I am very pleased with the quality and fit.
I don't agree with their no returns policy and the shipping is extremely slow, so they should change those two things if they want to stay competitive with other retailers, but I would order again as long as I'm not in a hurry for it.
