I've titled this the blue dress, because that's the color Hillary Swank wore to the 2005 Academy Awards. Designed by Guy Laroche, this backless dress is regarded as one of the most iconic red carpet dresses ever.

Works better with SDXL but it also works with Pony.

Start with 0.8 for strength.

Even though the original dress was constructed out of blue jersey, you can specify the color and fabric in your prompt.
