What do I wear? Casino night?

My friend is having a party at her house this Saturday, the theme is casino night. But I have no idea what to wear or what would go with the theme. Any suggestions would be greatly appreciate. I'd prefer if you could send links to cloths that would be good. But either way. I was looking at previous question that are similar. Alot of people suggested sequin dresses, but I'm full figured, that wouldn't look good on me. The last thing I want is to look like a disco ball. LOL. But any suggestion other then that would be great. Much thanks
