Dear Carolyn,

We regret to hear that you are having sizing issues.

On all our Dresslily product pages, below the product description, we offer a clearly marked size chart. We ask that all customers refer to this before purchasing. We encourage customers to use their exact measurements when selecting a size to ensure they choose the correct one.
We offer a 30 days warranty for returning the item to us for a exchange or refund. Please check it here http://www.dresslily.com/m-article-id-80.htm
For more details, please contact us on our support center with your order number.
