Ryan Gosling hasn't always been a Hollywood fashion icon. In 2006, he came to the premiere of his film "Half Nelson" wearing a tuxedo T-shirt. While you might appreciate the humor of his choice, don't take his action as fashion advice. If you have an important, formal event to attend and you want to make a good impression, go with the tuxedo over the tuxedo tee. This shirt hasn't been popular since the 1980s, and even then it was questionable.
While the classic tux is black and white, don't think that wearing these standard colors limits your options. You can choose a colored bow tie and other accessories you want to wear, and whatever happens, you certainly won't be underdressed!
