According to some of the Men's major Fashion houses a must add to your Formal wardrobe is the “Three Piece Tux” with a Black Over-sized bowtie.   "We are seeing a switch from the two piece to the three piece tux.  The big extra you get is a vest—which keeps you looking sharp when you remove your jacket, and the Big Bow will help accentuate the vest"- Robbie Mandel.  The three and a half inch Bowtie is one of the hottest items for this spring.
