Why does this happen with shapewear

[Highnone]

I have now tried on around 6-7 types, including Skims, John Lewis, Spanx etc

I am looking for something to hold my tummy in.

Everything I try on makes absolutely no difference, I just have like a sausage casing over me - but with still a big belly!

Im a Size 14 - often look pregnant

help!

I have the same issue.

We need to work on our core strength apparently and our belly will not look as pregnant
I'm still trying lol
