The Things You Should Never Wear to a Wedding

White isn't the only color that's off limits. We err on the side of caution when it comes to black. This one still maintains its relevance in mourning, so be careful of sending the wrong signals. Similarly, a bright, over-the-top color like red is flashy — as in flashy enough to steal the bride's thunder. But the thing with black and red is that there are many loopholes. Lighten up the look with a feminine pattern and you're likely in the clear. But as with anything, use your best judgment.
