Ideas for my year 12 formal dress?

don't get a long dress, get a short one, so it'll accentuate your lobg legs. i'm 5'10" and when i wear short dresses they make my legs look even longer lol. and if you want to stand out, get a bold color, like electric blue, hot pink or purple. or even do animal print, like cheetah, or leapoard. good luck finding what your looking for!
