Ms. Pacman have you tried the 'open bust' body suit ones? Those are the ones I've had the most success with, as I struggle a bit with the highwaisted ones being too long for my torso and curling down (and anything shorter can yes possible result in just pushing stuff up)
I have this (or the kohls lower end Spanx line) : https://spanx.com/collections/shapew...39773550706899, and I have a similar style by Maidenform. I do think it can help to size up a bit if it feels too constricting.
I get so many ads for shapewear in my feeds, I'll probably get more after writing this
