What to wear to a concert?

I am going to a Daughtry concert. I want to have kind of a rock look and stand out a little. I bought these capris (a href="http://www5.jcpenney.com/jcp/X6.aspx?GrpTyp=PRD&ItemID=185bc56&Ntt=almost+famous&hdnOnGo=true&Ne=4+6+1031+8+18+904+949+833&submit%20search.y=0&SearchString=almost+famous&submit%20search.x=0&N=4294959029&Nao=0&SO=0&PSO=0&CmCatId=searchresults)" rel="nofollow"http://www5.jcpenney.com/jcp/X6.aspx?Grp…/a and this necklace (a href="http://www5.jcpenney.com/jcp/X6.aspx?GrpTyp=PRD&ItemID=169b956&Ntt=decree+wings&hdnOnGo=true&Ne=4+6+1031+8+18+904+949+833&submit%20search.y=0&SearchString=decree+wings&submit%20search.x=0&N=4294959029&Nao=0&SO=0&PSO=0&CmCatId=searchresults)" rel="nofollow"http://www5.jcpenney.com/jcp/X6.aspx?Grp…/a and was going to wear a black shirt and some platform heels. But I was thinking maybe I should wear a y dress (nothing too fancy). I was thinking that might be too revealing but its a concert so why not. What do you think would be better for a concert? Thanks!!
