One more batter for team #6! I think both the colours of the dress and its cut make you shine. The defined waist, full skirt and cap sleeves do work wonders on you.
#5 is my least favourite. The fabric does not look as substantial as others, and I don't think the U neckline with very large shoulder straps look as good on you as either higher necklines with large straps (like 9#), or U necklines with thinner straps (like #1).
