Hi OP
I have that dress in the midnight shade, it is a fab dress and have had so many compliments on it, but i mainly wear it for work.
that said in the red it is much more racey and it has a nice lowish v at the back which you can't see in the picture.
i think you could def sex it up like Tethers says with bare legs and some great shoes. I have also seen the girls in LKBennett wear it with a belt.
I have an email voucher for 15% of at LKB at the mo, don't know how to do these personal message things yet but if you message me your email address I can send it to you, or if you use the code Launch online you get the discount too.
I have this dress which is fab and they do it in other colours too, a bit more pricey though.
