Your image lacks selective colorful accesories that you could turn to neon in Photoshop. Like you said, there's not much reds on your image to bring out like that.
A quick and easy way to achieve a similar effect is to use a duplicate copy on another layer, aply Motion Blur at the default linear setting and mask to reveal the sharper image. Then add an adjustment layer on color balance and work on "highlights" with the color you want to bring out.
I did that in 5 min. I worked on the highlights on reds, but there wasn't much to bring out besides patches of color on the corset.
Start by setting up a shooting where the model wears accesories of one color, even if different tones.
