Years ago remembering balls MOH and I attended in airforce messes, when a black tie do was specified we had no choice but to wear long dresses, meaning down to the ankle.

I think trends have changed now even in the military, and I think dress for the ladies is optional, so I think you would be okay in long or short. Just wear some stunning jewellary with whatever you chose. If you wear strapless, wear a pretty wrap, Im sure you will look great.

Have a lovely time. Plasmo x
