NWT Jovani gown. Size 6

Bought this dress to wear for a wedding and changed my mind but store policy is no returns. Never been worn, or altered with tag still on. Size 6 by Jovani. I would say it fits more like an 8. There is a slight pull in the ruching. I can send measurements on your request. From a smoke free home. 100 percent polyester and lined. Please ask me any questions!
