Can I Wear This Dress To A Wedding?

Whenever there's a post about wearing white to a wedding, I always post the same story:

One of my friends wore a dress that had a white top and a polka dot bottom to a wedding. In all of the seated pics (i.e. at a table), she looked like she was wearing white. Even though just the top of her dress was white from the waist up, it was a no-no.
 
No matter how you accessorize, jacket, belt etc the answer will always be no for any white, ivory or off white option to a wedding (unless bride specifically requests you wear white- as in an all white party)
