I wore these for 27 hours straight and my endometriosis-bloated stomach didn't even notice.
This is me wearing the leggings. ^^ It's also very worth mentioning that I was on my period when trying them on, and I knew I would be able to tell immediately if they were too tight on my abdomen. They did not fail the fitting room test. I felt zero discomfort.
Can you even believe? Because I could not.
