Asymmetrical black floor length dress

I wore this dress as a James Bond girl for a themed party. It’s got a pretty scandalous slit on the left leg, but because it is all black and floor length it balances out nicely as not too revealing. Fits me very nicely : I’m a size 10 and 36D Ps there seems to be some residue from some boob tape I used while wearing this dress. It has already been washed but seems to have remained.
