I want to look better then my sister at her wedding?

yes, don't ever forget something like that, good for you

Actually, I've seen wallpaper that has a candy apple red color (not blood red - this is a bit less orangy) and a sky blue that look pretty good together. It's a tricky combo, because it's the kind of combo where if you start wandering from the basic tint of each color, it's going to look awful. But the real problem if you want to do it is the black. This just doesn't belong. You'd want an ivory or whitish color for accent. PS - I just googled the words red and light blue wedding (without quotes) and then clicked on images. There's a ton of stuff out there!

Sure go ahead and do that and show everyone that you are a shallow, petty, vindictive person. Two wrongs never make a right and to give evil for evil is a recipe for inviting even more evil into your life. She might have been trying to get attention but perhaps she was hoping to attract someone at the wedding. In any event I would show that I was the classier person by not trying to show her up on her wedding day. you know how that made you feel so why do it to someone else keep the moral high ground and do the right thing

No, you should not.

I know it is very obvious for you to think in that direction, but hold on and ponder over it for a while.

Just imagine that at your wedding, everyone must have noticed this about her, the way you did. And, everyone must have thought the same the way you have thought about her. Needless to say, this is surely not a good opinion about any girl.

Then, why do you want to repeat the same thing and let people think bad about you too?

Instead, be sober and let people think about your greatness. This will bring you praise.

Leave the revengeful idea.

No, because you are a better person than she is. It must have been awful for you, but people will have judged her as having bad taste. They will think the same about you if you try to upstage the bride. Your sister will also say "But you said I could wear anything?"

If you still feel angry with her, it is better not to go.

It's still wrong. She probably didn't take your wedding seriously because it was so small, and don't get me wrong that was messed up for her to do no matter what the circumstances, but you need to be the bigger person here. Altering my brides maid dress a little to stand out from the other brides maids would be as far as I would go.

If depends if you're a rebel or not. :)

If you're setting out for revenge on your sister, do you actually want to do this? Is your sister that bad?

Morally, most people would probably say something like 'two wrongs don't make a right'. Ask yourself, is it important to you, even now. Do you want to act like a child's sibling rivalry?

So you actually WANT to look like a selfish jealous attention whore?

Take the high road here, two wrongs don't make a right

I thought that every kindergarten child knew that two wrongs don't make a right.

Neither of you is mature enough to be married. I hope you don't have kids that you're setting a horrible example to.

She ended up looking like a attention whore, and now you want to repeat that mistake? Just proves you are related.
