What would be a good prom dress for me?

Im 16, 5'5 and 105 pounds.... so im pretty petite. Im skinny everywhere and i barely have any shape. My cup size is A and barely have clevage with a good push up bra... but a will most likely be wearing a strapless bra. Im pale and have green eyes with long dirty blonde hair. It should be a longer dress... and if you have ideas for shoes that would be great :) Any suggestions? Pictures would be helpful :) Thanks!
