I am going to a black-tie wedding in February and have in mind the exact dress I want to wear. Unfortunately, I've not found a RTW version that's less than $400. Do you know a pattern for this style dress? The essential part of course is the low back.

I have the worst luck searching through all the thousands of patterns out there for a specific idea.
