A beautiful three tier all pink cake, with edible silver or gold glitter or rhinestones to symbolize the stars in the night.
Maybe The bottom layer can be light, the second tier, a little darker, and the top part of the cake like a dark pink to sort of give the illumination of a shadow in the night?
Food for thought ;)
More ideas on this would be loved! So anyone who would like to share their ideas don't be shy!
