Okay, this one is kind of a no-brainer, but it bears repeating: Do NOT, under any circumstance, wear white to a wedding (unless you're the bride, of course). Off-white? Nah. Eggshell? Nope. Ivory? NO. Wearing any variation on the color white is a big fat wedding DON'T. You really, really don't want be that girl who looks like she's trying to upstage the bride!
