I have always loved the idea of a tuxedo inspired piece as an alternative for a more formal event. It instantly gives a clean, polished feel to any outfit, but done wrong can be disastrous.
For me, I like to pick either a blazer or a pant to create this look and give it my own style. The addition of a statement necklace over a sheer lace top made it a bit more interesting than just pairing a matching blazer. Time to hit the town!
