Bra for dance performance

I have a showcase coming up in a month . I'm performing 2-3 hip hop choreo which requires lot of jumping and stuff so I was wondering how to keep my chest from bouncing. Usually i wear a sports bra for practices but the thing is my sports bra is very visible. it has front zipper and multiple straps and I can see the outline over my top . for practice its fine but for performance i don't want it to be seen but i also don't want to lose support that it gives . Have heard about boob tape but how supportive is it ? what does usually plus sized people with big chest do for performance? for reference I'm 40D
