Her wish to walk down the aisle in a Vera Wang wedding dress led instead to a lawsuit.

Stephanie Xethalis bought her $10,995 wedding dress from the chic designer’s Madison Avenue shop in 2014, according to court papers.

Now, in a Manhattan Supreme Court lawsuit, Xethalis and her dad, John, say Vera Wang “failed to deliver the wedding dress” they agreed on.

They’re seeking unspecified damages. A Vera Wang rep didn’t return messages.
