My dress for the wedding im attending?

I think it is a great color and wearing bright colors to weddings is very in (although it depends a little on time of year). As long as you feel great in it, do it! If you feel like you will be really self-conscious, don't do it though, or you will be spending the whole night worrying about your dress and not having fun. Honestly, no one but you will care what you wear unless you are the bride, so do what makes you most happy! Good luck!
