This is a navy dress with a frill at the waist. I bought it for a wedding I was invited to shortly after giving birth, but I ended up wearing a different dress, so it's new and unused. Size is M. It can be used for various events and invitations, not just bridal occasions. There is a nursing hook on the chest. *Although it is new and unused, please understand that it has been stored at home before purchasing. Thank you for looking.
