Handing chest area on low cut / neck cosplay

Hiii, lil bit of context, I'm a transgirl and wanna start cosplaying!!! I'm pretty early transition so im still flat as a board but I really wanna cosplay Violet (Kasumi) from persona 5 royal. I'm worried about my chest tho as there's nothing there, I wanna make the cosplay as close to character as possible (and just to deal with dysphoria). Normally with clothes that cover the area I just use padding but I can't for this. Does anyone have any suggestions? Will using makeup to create a shadow help? I'm also planning to use the leotard as a part of a pole dance routine for a competition as well, so any suggestions that will work while moving about a lot would be even more helpful!!!

I've included a photo of the character and of someone cosplaying the character from Google images. Would really appreciate any advice or suggestions!!! Thank you so much in advance!!!
