Sofia Vergara in Zac Posen Pre-Fall 2014: A BIG trend of the night--the full-on ball gown. And Sofia Vergara is showing it here with this strapless gown from Zac Posen Pre-Fall 2014 collection. The gown features an UBER tight torso/corset that is kept fitted to the hips and then the fullness begins, created by many large godet panels. It is DRAMA with a capital "D". And I think it works on her. I also think that gorgeous turquoise statement-making necklace is perfect for it.
