High school Graduation Question?

My high school graduation is in June, and I still haven't picked out a dress. All my friends have their dresses/tuxes picked out and I'm the only one without one! I'm having trouble figuring out which color looks best with my hair color and skin tone. I have really thin blonde hair that has a natural curl to it, and my skin is very fair, but I tend to blush a lot so I don't need any extra color in that area. My friends are saying my dress should be light pink, or ivory. Something light, but I'm not so sure.

I've been thinking about wearing this dress, or something along these lines:
