Uneven waist, what to do?

I’ve never heard anyone talk about this but for some reason it’s making me insecure. I’ve been working out and realizing that my left side (waist) is shaped like an hourglass, but my right side is more like a straight line. I dance and don’t have enough muscle energy or something to do the same techniques with the right side like I do with the left which I guess could be the reason. Anyone have this happen?

Will massaging the right side in help it look like that over time? I don’t want to wear a waist trainer or anything.
