Query: disappointed

The dress material is not good, polyester, and cheap even though it looks good online. In addition the vendor is in China. This means you have to be careful with your cost of returning the item because of custom. The process is a pain. I was very disappointed. I believe they should disclose that the item is being shipped from out of the United States and you might possibly encounter additional cost.
