I'm considering a thong under a catsuit for my dress:
This or this:

https://skims.com/products/core-control-thong-sand?variant=29820168011836
Under this:

(love Spanx but this is only a level 2 support - needing maximum "suck" in my lower tummy. For reference, my dress was shared in my previous post)
