HELP!

Ok guys, so I'm in need of some advice. My end of school prom/river cruise is coming up and I have a few decisions still to make regarding outfits!!!

Regardless of the fact that this may not be my final dress (long and distressing story...) I am not sure what shoes to pair with it.

Do I go for black or match the silver?
Do you have any other genius ideas? because to be honest I am at a loss.

Another dilemma I face with this beautiful number is the gorgeous back (or lack of it!)

I have done my research and the trusty m&s (uk only I suspect) has a pretty good looking stick on bra.

Now the prospect of a stick on/backless bra to the more blessed, shall we say, comes at quite an intake of breath. However the reviews on the website seem to be positive and promising...

Please let me know of any suggestions you may have or experiences with the bras in question!

I shall update soon on the matter and hopefully find the solution! :)

Over and out.
