It has been a stunning weekend of wedding fashion for Sofia Vergara so far!
Ahead of her Sunday wedding to Joe Manganiello, the Modern Family star donned a gorgeous party dress by Mark Zunino for a Saturday night cocktail party. The beautifully designed confection is definitely one of her most breathtaking looks from the celebrations and only ET has the exclusive look at how it came to be.
The cocktail dress features hand-beaded French chantilly lace over blush silk crepe with an off-white blush pink layered silk organza skirt. And it was all built around a custom corset so it hugged the actress' famous curves perfectly.
"When Sofia asked me if I felt this style dress, with such a full skirt, might be a bit too 'young' for her, I told her NOTHING says 'I'm so in love' like a sexy party dress!" Zunino tells ET exclusively. "She answered laughingly, 'You're right!'"
See his gorgeous sketch below:
And Zunino was right! The sexy dress totally nailed the festive atmosphere inside Breakers Hotel where Sofia and Joe's family and friends gathered for the party. The full skirt was the perfect accessory as Sofia danced to the music of Colombian singer Jorge Celedon.
