Zulily does not house most of its inventory. Most things need to be shipped to them first. When you order from them, you should expect that it will take longer than when you order from an actual store. I have ordered many things. Twice Zulily could not get the product and cancelled my order. Both times, they refunded my money and gave me extra store credit for my inconvenience. The sizes vary depending on the brands you purchase. If you are in a hurry to get an item or can't afford to take a risk, it may not be a good company for you. If you have time to wait & can withstand the risk you may find some good deals. Dresses, tops, legging, & home goods are pretty safe purchases. Remember you aren't going to pay $20.00 &receive a $300.00 designer garment.
