You will here screams and cries from all over the world haha I wish, I don't get that many votes :)

Find the old stripper song, set up the video camera with that playing in the background and show how much weight you have lost.
Do it as a spoof, have the camera cut away at the right time so you don't show more than you want to, lots of swaying hips and belly rolls., suggestive sliding the gown down the arm, and back up again.
In other words, make a funny video and have a laugh doing it.

One or both daughters would probably jump at the chance of helping.

Omg my daughter's would freak out haha seeing there mum strip would turn there stomachs and everyone else, made me giggle though :)
