Fancy dress ideas - movie theme

[KnockMeDown]

I'm hoping for ideas and inspiration. I have just bought this dress, which I am delighted with. I plan to wear it to a fancy dress party, where the theme is movie stars or film characters. So I need some ideas of what would fit with this dress. And how I could accessorise it. Can anyone help?

Thank you!

I know it's not quite the right shape but could you accessorise it as a flapper dress - feather headband and long beads - and go as Daisy from the Great Gatsby?

Thank you Santa will look her up.

Any other ideas?

Audrey Hepburn in Breakfast at Tiffanys with the right accessories and hair?

It could do late 20s early 30 s, so could be Fantastic Beasts and where to find them.
