Re: wearing same colors as the bride... thoughts?
^Like a few people have mentioned in this thread, when you're the bride, you are THE bride.. up on that stage and center of everyone's attention. Even if the entire guest list shows up wearing same colors as you, it's still your day and everyone wants to look at you, not what other 200-300 people are showing up in.
Your cousin just overeacted it seems. It happens.
