Prom help Watch
It may not find you the dress, but it will probably find some similar ones.
You will certainly be the bell of the ball wearing that, what are you thinking about wearing to accompany that?
I know there is a company called pronuptua and young, that specialise in wedding and prom gowns, what about places like Debenhams, other than that I think it is just a case of trolling the net.
Good luck, I think it would be worth the effort to find that dress. X
I recently bought a lovely cocktail dress in Harrods, if you dont mind spending the money, might be worth looking at there website. X
