Dirty Dancing (40th) themed party ideas?

[bouquetofpencils]

I am having everyone dress up in the style of the film Dirty Dancing for my big party (obvs I will be Baby). Please do you have any ideas for how I can dress the function room? Cheap as possible as still on maternity leave so low budget do! Have about a month before do.
Thank you in advance!

Get a schematic of the dance steps for the Merengue and mark it out with footprints and arrows on the dance floor.
Use lining paper to make palm trees on the "stage" and add white trellis at the sides.
Bring a watermelon.

lots and lots of life sized photos of Patrick Swayze in THOSE trousers...

Have watermelon table centrepieces... Whole watermelons
